General Science / What is the GPS of the highest point of BIG BEN using 3 percengates: (%, %, %) ?

« on: 21/03/2024 09:30:42 »

GPS point is Latitude, Longitude and Altidude.
Since latidude and longitude can be seen as two polar coordinates angles both within the interval 0 to 360 and altitude can be seen as an interval between, zero, center of the planet and K?rm?n line, let's say: 100 km, to make it more metric.
For instance Big Ben meridian intersection in the equator (prime Meridian in the equator) at sea level would be: 0%, 0%,(6371000/ {100000+ 6371000})=  98.454643 %.
So, if that point in the equator would be GPS: (0%, 0%, 98.454643 %) what the Big Ben highest point would be?

Note, one of the next cities in the two angles from zero to 360 would be Oslo, because is more up North and East. You get it.

PS - 24 digits would be used for GPS/LLA: (xx.xxxxxxxx %, yy.yyyyyyyy %, zz.zzzzzzzz %).

Physics, Astronomy & Cosmology / How many stars in the most dark sky without {The_Sun-0001} naked eye with 20/20!

« on: 24/01/2024 11:14:42 »

Hello,

I am a computer scientist from London South Bank University.
(I am working on some interesting projects, namely an improvement of the Sun-Dial-Clock, casting both the Sun and the Moon with 24/7 neon/like RED-BLUE handles, the 24h cycle and the 27-29 days cycle. We think the DIAL shall be a vertical bar cylinder with 11.11 centimetres of diameter and that at the top we shall have a WHITE LIGHT BRIGHT torch with diameter 11.11 centimetres pointing to the centre of the smallest circle that can contain all the point-stars of ORION constellation that is well signed to our future bionic race, the ancestral Aryan-Zion Race of the past).

I need an answer from NASA and the European Space Agency (ESA) to this question:

"In a VR environment that emulates the number of visible stars for a quite average human naked eye with 20/20 vision, how many stars are visible? Assume the light of the sun, Star_0001 can all be suppressed and that the light from our planet, Earth, and its natural satellite, the Moon, can also be supressed in the VR sky."

If possible provide a list of all those stars, starting with the Sun: 0001-xxxx_

Explain all of your rationale and provide sources. How many stars can be seen, dark sky, naked eye, average human vision 20/20.

General Science / What is the smallest laser able to melt iron made by nanotechnology?

« on: 26/05/2023 06:41:24 »

What is the smallest laser able to melt iron made by nanotechnology?

It seems an interesting example application of nanotechnology to hold in mind and to think about and for that matter I am willing to know more about implementing such nanomachinery. The smallest laser able to melt iron would be a device that can generate a high-intensity beam of light at a wavelength that can be absorbed by iron and cause it to reach its melting point, which is about 1538 degrees Celsius.

One possible way to create such a device is to use selective laser melting (SLM), which is a technique that can produce near-full density metallic objects by completely melting powder particles with a laser beam. SLM can be used to create complex shapes and structures with high precision and accuracy, and it has various applications in fields such as aerospace, automotive, biomedical, and more.

However, SLM is not a simple process, and it involves many challenges and parameters that need to be optimized.

For example:

1)  The materials properties, such as composition, size, shape, and distribution, affect the melting behavior, density, porosity, and mechanical properties of it.

2)  The laser parameters, such as power, speed, spot size, scanning strategy, and hatch distance, affect the thermal gradients, residual stresses, microstructure, and surface quality of it.

3)  The process environment, such as temperature, pressure, atmosphere, and shielding gas, affect the oxidation, evaporation, spattering, and contamination of it. Creating the smallest laser able to melt iron would require careful selection and control of these factors and I am looking for any information about the exact size or shape of such a device.

I hope to learn more about the smallest laser able to melt iron.

General Science / [Ask ChatGPT] - How can driving improve with sensors in 3 groups of 3 vertices?

« on: 15/04/2023 15:36:08 »

Title: Revolutionizing Driving Safety with 9-Vertice Sensor Systems and VR Simulators
Introduction:
With advancements in technology, the automotive industry is constantly exploring new ways to improve driving safety and efficiency. One of the latest innovations is the 9-vertice sensor system, which combines wrist bracelets and steering wheel sensors to monitor driver hand positions and movements. Coupled with the immersive capabilities of Virtual Reality (VR) simulators, this innovative technology has the potential to transform the driving experience and significantly enhance road safety.

The 9-Vertice Sensor System:
The 9-vertice sensor system consists of two bracelets worn by the driver and three sensors positioned on the steering wheel, with both the bracelets and the steering wheel sensors forming equilateral triangles. The bracelets are equipped with chips and Bluetooth technology, enabling them to communicate with the sensors and transmit precise distance measurements between each of the points on the equilateral triangles.

This real-time data can be used to monitor driver hand positions, grip strength, and steering input, providing valuable insights into driving behavior and performance. The system can also be integrated with vehicle control systems, allowing for real-time feedback and assistance to help drivers maintain proper hand positioning, avoid distractions, and maintain better control of their vehicles.

The Role of VR Simulators:
Virtual Reality (VR) simulators are an invaluable tool in enhancing the capabilities of the 9-vertice sensor system. These simulators can replicate various aspects of real-world driving, providing users with an immersive environment in which to practice and refine their skills. By incorporating the 9-vertice sensor system into a VR driving simulator, users can visualize the relationship between their hand movements, steering input, and vehicle control.

In addition to practicing basic driving maneuvers, VR simulators can offer customizable driving scenarios, such as urban streets, highways, or adverse weather conditions, providing users with a comprehensive training experience. With real-time feedback on hand positioning and steering input, users can make necessary adjustments to improve their driving skills and increase confidence.

The Future of Driving Safety:
The integration of the 9-vertice sensor system and VR simulators has the potential to revolutionize the driving experience and significantly improve road safety. By providing drivers with valuable insights into their hand movements and steering input, this technology can help prevent accidents, reduce driver fatigue, and improve overall driving performance.

Moreover, the widespread adoption of this technology could lead to the standardization of steering wheel sizes and forms, making driver patterns more uniform and easier to interpret. This, in turn, could result in safer roads and a better driving experience for all road users.

As technology continues to advance, the automotive industry must embrace innovations like the 9-vertice sensor system and VR simulators. By investing in research, development, and implementation of these technologies, we can work together to create a safer and more efficient driving future for everyone.

An additional approach to improve the efficiency and accuracy of the system is the use of an imaginary cube with a metric grid. This cube, with one meter sides and subdivided into millimetric cubic cells, can help determine the configuration of the 9 vertices at each instant. Drivers can visualize this imaginary leveled and metric cube, facilitating the understanding of hand and steering wheel positioning in relation to this grid.

This innovative approach makes the system easier to understand while simultaneously allowing for the creation of efficient and accurate algorithms to optimize the driving experience and enhance road safety.

In conclusion: how can driving improve with sensors in 3 groups of 3 vertices?

General Science / [Asking ChatGPT] Could newborn childs now learn perfect pitch while they sleep?

« on: 12/04/2023 17:50:18 »

Possible article by ChatGPT:

New research suggests that exposing newborns to specific sounds during sleep may enhance their musical abilities, including perfect pitch.

According to a team of scientists from top universities and music schools around the world, including Harvard, MIT, Juilliard, and Berklee, listening to 12 randomly selected notes played at a low volume during sleep may stimulate brain circuits involved in processing music and sound, especially during critical periods of development in the first years of life.

The sounds consist of pure sine waves, which have a simple and regular waveform, and were recorded with a free audio editor called Audacity. The 12 notes correspond to the Western music scale, starting with C4 (middle C) and ending with C5 (an octave higher), and are played for five seconds each, followed by a brief fade-in and fade-out period of silence.

The 12 notes are played randomly, synchronized with the atomic clocks of the Universal Time Coordinated (UTC), at a rate of 12 samples per minute, 24/7, for as long as the babies sleep. The sounds are delivered through a popular device called Amazon Echo, using the Alexa app, which can be controlled remotely and adjusted for volume, tone, and other settings.

To make the experience more engaging and memorable, the researchers used the voices of different virtual assistants from a company called Eleven Labs, which specializes in natural language processing and text-to-speech technology. The voices were selected based on their gender and accent, with seven white notes (C, D, E, F, G, A, B) voiced by a female and five black notes (C#, D#, F#, G#, A#) voiced by a male.

The voices announce the number of each note before and after it is played, using clear and consistent English pronunciation, with an emphasis on the frequency of the note in Hertz, rounded to two decimal places. For example, C4 (40) is announced as "C four, two hundred sixty-one point sixty-three", and so on for the other notes.

The researchers plan to monitor the development of the infants who listen to the sounds and compare them with a control group of infants who do not receive any auditory stimulation during sleep. The measures will include behavioral tests, brain scans, and surveys of musical skills and preferences, starting from the age of six months and continuing up to five years.

The researchers hope to confirm that exposing infants to specific sounds during sleep can enhance their musical abilities, including perfect pitch, which is the rare ability to identify and reproduce a musical note without a reference tone. Perfect pitch is more common in people who started musical training early in life, suggesting that it may be a form of neural plasticity that can be enhanced or inhibited by environmental factors, such as exposure to music or language.

The researchers also hope to explore the potential benefits of using similar sounds and voices to enhance the sleep quality and cognitive development of adults and elderly people, as well as to improve the performance of athletes, students, and professionals who need to concentrate and memorize information for long periods of time.

The findings could have implications for the design of audio systems and apps that aim to improve the well-being and productivity of individuals in various contexts, from homes and hospitals to schools and workplaces. The researchers caution, however, that more studies are needed to confirm their hypothesis and to rule out other factors that may affect musical development and cognition.

The researchers also acknowledge that not all babies may benefit equally from the sounds and that some babies may even be disturbed or irritated by the sounds, especially if they are too loud or too monotonous. The researchers encourage parents and caregivers to use their discretion and to consult with their pediatricians or audiologists before exposing their babies to any new sounds or devices.

The researchers also stress that the sounds should not be played loud, with volume 3 of amazon echo being recommended under normal circunstances.

Anyone can record the 12 sounds using pure sine waves of Audacity free software and use female voice for seven white notes and male voice for the five black ones.

General Science / [Asking ChatGPT] Could this design improvement to cold fusion accelators work?

« on: 11/04/2023 19:31:03 »

Hellion's plasma accelerator used for cold fusion has the great advantage of being quite compact comparing to other structures but imagine it the whole structure would curve around itself in a vertical coil and plasma concentrated in a triad of the circles in the coil were all compressed down from the upper part and up from the downer part colliding all in the center? Could this keep it compact and make the collisions stronger?


It seems like you're proposing an interesting modification to the Helion's plasma accelerator design for cold fusion. In general, increasing the compactness and collision strength of plasma within the reactor can be beneficial for achieving fusion.

To evaluate your proposal, let's first break it down into its components:

Curving the entire structure around itself in a vertical coil.
Concentrating the plasma in a triad of circles in the coil.
Compressing the plasma from the upper and lower parts to collide at the center.
In principle, it's possible that curving the structure into a vertical coil could have some benefits. For example, it might lead to a more efficient use of space or magnetic confinement. However, without more detailed simulations or experiments, it's difficult to predict the exact effect of such a modification on the performance of the reactor.

The idea of concentrating plasma in a triad of circles in the coil and compressing it from above and below is also interesting. It seems like you're suggesting a mechanism to increase the plasma density and pressure, which could potentially lead to stronger collisions and higher fusion rates.

However, there are also potential challenges to consider:

Engineering complexity: The proposed design might be more complex to build and maintain than the current Helion design, especially considering the need for precision in the alignment and control of plasma behavior.

Plasma stability: With a more complicated geometry, maintaining plasma stability could be more challenging. The confinement and stability of plasma in fusion reactors are critical factors in achieving fusion.

Energy input: The proposed design might require more energy input to compress the plasma from both the upper and lower parts, which could offset any potential gains in fusion performance.

Efficiency: It's uncertain whether the proposed design would lead to a net improvement in fusion efficiency, as the additional complexity could introduce new inefficiencies or challenges.

Overall, the idea is intriguing, but a thorough analysis and experimental testing would be necessary to determine its feasibility and potential benefits for fusion. Engineers and physicists working in fusion research could potentially use this concept as a starting point for further exploration and development.




Daniel Alexandre
No, I mean all the circles of the coil would maintain the concentrated parts of the plasma in the same points of a triad (equilateral triangle vertices) when the coil is seen from the top so the distances between them were all pretty much the same and comparable.

Ah, I see. In this case, you're proposing a vertical coil design in which the concentrated plasma regions in each circle of the coil align to form an equilateral triangle when viewed from the top. This would maintain equal distances between the concentrated plasma regions in each circle.

This design could potentially offer some benefits, but it would still have some challenges to overcome. Here are some thoughts on your proposal:

Magnetic confinement: Arranging the plasma regions in an equilateral triangle could provide a more symmetric and consistent magnetic field configuration. This might help with the confinement and stability of the plasma, which are crucial for achieving fusion.

Plasma collision: By concentrating the plasma into these triangular regions, it's possible that you could increase the collision rate and pressure, which might improve the fusion rate. However, it's important to consider the trade-offs between increasing the collision rate and maintaining plasma stability. A balance must be struck for efficient fusion to occur.

Engineering complexity: This design would still introduce additional complexity compared to the existing Helion design. The precise alignment and control of plasma behavior within the coil structure could be challenging to achieve and maintain.

Efficiency and energy input: As mentioned before, it's uncertain whether this design would lead to a net improvement in fusion efficiency, given the additional complexity and potential challenges it introduces.

Ultimately, the feasibility and effectiveness of this design would need to be assessed through detailed analysis and experimental testing. Fusion researchers could explore this concept further to determine its potential benefits and challenges. If the design proves to be advantageous, it could contribute to advancements in compact fusion reactor technology.

General Science / [Asking ChatGPT] Why would LED ligths in cargo ship is a good idea?

« on: 26/03/2023 11:58:08 »

Why would LED ligths in cargo ship is a good idea and not spend much fuel?


ANSWER:

LED lights are a good idea for cargo ships because they are highly energy-efficient and long-lasting compared to traditional lighting systems. LED lights consume much less energy to produce the same amount of light, which translates to a reduction in the amount of fuel needed to generate the electricity to power them. In addition, they have a much longer lifespan compared to traditional lighting systems, reducing the frequency of replacements and maintenance.

By using LED lights to promote the growth of kelp in the ocean, cargo ships can reduce the need to use fertilizers and other harmful chemicals, which can be detrimental to marine life. Furthermore, kelp can help sequester carbon dioxide, potentially mitigating the effects of climate change. Overall, using LED lights is a more sustainable and environmentally friendly approach to promoting kelp growth in the ocean.

How many lux is 1 million bright white LED lights?

The brightness of a single LED light can vary, so it is difficult to provide an exact answer. However, on average, a single LED can produce about 1 to 10 lumens of light.

Assuming an average LED brightness of 5 lumens, 1 million bright white LED lights would produce about 5 million lumens. To determine the lux level, you would need to know the area over which the light is being spread. For example, if the 5 million lumens were spread over an area of 100 square meters, the lux level would be 50,000 lux (5 million lumens / 100 square meters).

General Science / [Asking ChatGPT] How could mobile device banking app make SQRL popular & secure?

« on: 24/03/2023 08:19:27 »

What could be the most likely and important banks in the world with great UI/UX mobile banking apps, that could implement the SQRL of Steve Gibson, making SQRL all of a sudden popular to millions and millions of humans that would start using it to login to most WordPress websites? List 5 banks.

As an AI language model, I do not have the ability to predict the future or make specific recommendations on which banks may implement the SQRL authentication system or have the best mobile banking apps. However, I can provide some general considerations and examples of banks with strong mobile banking apps:

JPMorgan Chase: JPMorgan Chase has a highly-rated mobile banking app that offers a range of features, including mobile check deposit and the ability to view account balances and transaction history.

Bank of America: Bank of America's mobile banking app has also been highly rated for its user experience and range of features, such as bill pay and account alerts.

Capital One: Capital One's mobile banking app offers a user-friendly interface and features like mobile check deposit and the ability to lock and unlock debit cards.

BBVA Compass: BBVA Compass has a mobile banking app that is known for its user-friendly design and features such as fingerprint authentication and mobile check deposit.

Ally Bank: Ally Bank's mobile banking app has received positive reviews for its ease of use and features like mobile check deposit and real-time transaction alerts.

It is important to note that while these banks have strong mobile banking apps, it is not guaranteed that they will implement the SQRL authentication system. The adoption of new authentication systems often depends on a range of factors, including security concerns, cost, and user demand.




Daniel Alexandre
Now explain how the SQRL client could be integrated in a banking mobile app and be audited by independent programmers foundations like Apache.org to make it more reliable. And how wordpress websites could all of a sudden make it very popular with mobile banking apps?
The SQRL client could be integrated into a banking mobile app as an additional authentication option for users. When a user logs in to their mobile banking app, they could be presented with the option to use SQRL as a more secure and convenient authentication method. The user would need to have previously set up their SQRL account and generated a unique identity token on their mobile device.

To ensure the reliability and security of the SQRL client, it could be audited by independent programming foundations such as Apache.org. This would involve a team of expert programmers reviewing the SQRL client's source code and ensuring that it is free of vulnerabilities and backdoors that could be exploited by malicious actors. The audit could also involve a review of the cryptographic algorithms used by SQRL to ensure that they are strong and secure.

WordPress websites could make SQRL more popular with mobile banking apps by integrating it as a login option for users. WordPress site owners could implement a plugin or module that allows users to log in using their SQRL identity token, in addition to other authentication methods like passwords or two-factor authentication. This would allow users to log in to WordPress websites securely and conveniently, without needing to remember complex passwords.

By integrating SQRL into mobile banking apps and WordPress websites, users would have a more secure and convenient authentication option that could help protect them against hacking and identity theft. The use of independent programming audits and reviews would also help ensure the reliability and security of the SQRL client over time.

[EDIT]: SQRL (Secure Quick Reliable Login) allows users to have many pseudo-IDs on the web using a single master (password) private key integrated in a mobile app than then will scan a QR code, for instance in a WordPress forum.[ It is the brain-child of Steve Gibson, from podcast SECURITY  NOW

Why does SQRL call the nonce a rodent NUT? Isn't that nuts?
The term "rodent NUT" is actually a play on words that Steve Gibson, the creator of SQRL, came up with to refer to the nonce used in the authentication process. In SQRL, the nonce is a random value that is generated by the client and included in the authentication request to prevent replay attacks.

The term "rodent" is used because the nonce is a small, seemingly insignificant value that scurries around the protocol like a small rodent. The term "NUT" stands for "Number Used Once," which is a cryptographic term that refers to a value that is only used once for security purposes.

So, the term "rodent NUT" is actually a playful and creative way of referring to the nonce value in SQRL, and is not meant to be taken literally or as a serious security term.

4) The column pipe is a triangular prism that fits perfectly inside the inscribed circle of each of the 6 triangles of an hexagon that fits a circle with 0.01 meters of diameter (10 mm). This detail is important in terms of showing the pipes could be put in a very regular hive configuration (6 columns = 1 hexagon that fits a circle of 10mm diameter).
5) Extra note: the column pipe can be made of an affordable material ideal for the purpose and it can be made modular using a simple joint that lets smaller pipes be joint promptly and conveniently.
6) The thickness of the walls of the pipe are quite thin. Let's say, 1mm of thickness if we used copper.

How much water leaks from each of these very cold and high "triangular prism" column pipes that can be further put in a hexagonal hive configuration of 6 pipes per hexagon (3 with liquid flowing up and 3 with liquid flowing down)?

Note: water will condensate around the pipes because the pipes will be much colder than the air around them and air has always some humidity.

[EDIT] [Final note]: To have pure water at home out of thin air you only need to fill a vertical tube with very cold alcohol (from your freezer) and water will leak down.

New Theories / Metric system, Normal temperature: 440/12 Amb | Amber Heard, °C Degrees Celsius?

« on: 07/09/2022 20:38:23 »

1) 20°C used to be the NTP temperature. But since it is the case that that being the Normal temperature in NTP, metric system, is a bit random, I consider it better to use 440/12 (°C) instead. And, as Mr Fahrenheit and Mr Celsius, are certainly welcome, in our family and in History, please let me say that we shall from now on prefer saying instead: 36.7 Amb or 36.7 Ambs. Unless, of course, when we are not with normal temperature and/or are rather dead and/or with fever.
Moreover, no doubt I consider the recent sentence of my beloved Amber (the bright author of the December 2018 Washington Post op-ed) quite unfair. The normal pressure doesn't seem to require any change. So, 1 atm.
Is it ok? It is a bit of a fusion. Like when someone marries and has more babies... I feel it too. Of course...
Mozart Chocolate Liqueur: 0% Alcol, 0% Caff, 9.9% Cacao powder, 89% Coconut Milk and Water, 1% Peanut butter, 0% Nicotine, 0% Taurine, 0.1% Xylitol. 
Well, probably a few of your nuts and berries as well. Shall it be the tagline? Or: "Keep it in your very Alcol Sugar Diesel Solar Cranky Flask Fridge with external AWG!"
Making any sense?

P.S.- Outside of the fridge we will probably have a copper tube curve in 3D, a bit like a line drawn on paper without lifting the pencil. Alcol (ethanol alcohol) probably at:
-100 Amb. That is, at minus one hundred centigrades. And flowing at 1 meter per second in a closed circuit, with holes A and B separating the interior from the exterior of the fridge and having it keeping our flowing liquid refrigerated.
Unknows:
a) Shall the section of our long curved tube, to fit our ideal AWG cube, be the polygon circle or some other regular polygon like regular triangle, regular square, regular pentagon, or... ?
b) Ideal external/maximum diameter that passes by the center.
c) How twist/curve our very long tube of copper with very cold alcol inside?
d) What is the ideal spacing and amount of all of the interstice's air?
e) Is there a better liquid to be used inside the outside pipe? Does it need to be metal. If not, could it be PVC, for instance? (Probably Google and Google Deepmind will be able answer in a very short time.
f) How much percent of water (of a metric cube) do we get in 24 hours, at NPT, as mentioned above? What about water with added sugar, at just about the turning point of total saturation, if we have that amount of "sugar water", how much percent of the atoms is coming as alcol with a bit of electricity and the fermentation process.
g) I also did invent a vertical scale and a horizontal one to measure weight. A layer of alcol in a quite calibrated piston setting that does not leak or wear out and can last for many ages if treated well. That, lenses and mirrors.
Periscope, yes!
h) My will is that Rice University (in Texas) patents. And my family ends up having some of those royalties, coming from it and from the world of Engineering and consumer electronics in general.
