New Theories / Re: Can scientific beliefs be compared to religous dogma?

« on: 20/10/2018 08:28:48 »

No i am a retired engineer, with very little science, & not much math. I like to have an intense interest for a few years & then move on to something new, & at present my main interest is aether (which requires that i try to understand the enemy (Einstein)).I am very impressed & awed with~by the intelligence of scientists, oldendays & modern, & wish that Einsteinism be quickly dumped so that science advances. My heroes are Cahill, Ranzan, Crothers, Demjanov, Michelson, Miller, Sagnac, Ives, Lorentz, Wallace, Builder, Dingle, Arp, VanFlandern, Allais, Esclangon, Munera, & about 20 others.

I think this youtube channel has some materials you might find interesting.

New Theories / Re: Universal Utopia?

Are you using google translate?

No. If you find my posts sound strange, perhaps because English is not my native language. Besides, I often use mobile device to type, with occasional connection problem. So I had to type and post quickly to save my core messages. Only then I reviewed and made corrections. That's why you can see that my posts often changed.

That CAN'T be true! / Re: Tides is the result of the rotation of the Earth and whirlpools

« on: 04/06/2018 15:13:33 »

I think this video explains tide well. The title is "What Physics Teachers Get Wrong About Tides!"

The summary is that difference of gravitational force between nearest and furthest point on earth in earth-moon axis is too small to be the main cause of tidal bulge. Instead it is caused by the accumulation of forces on points outside of earth-moon axis.

What do you think?

They will pass through each other in this case, as if nothing is coming from the other end.

Physiology & Medicine / Re: Does an individual's mitochondria disappear?

« on: 02/04/2018 11:21:54 »

So, since I don't have sisters, and my mother's sisters didn't reproduce, and I only have sons who have sons am I to understand that whatever of me is physically present on this planet will not continue further? In other words, my only chance of a specious immortality is negated by biology?

You can donate your mitochondria, like in this case :

General Science / Re: Neutral has 0 voltage, so how does current flow?

« on: 15/01/2018 21:49:13 »

Okay thanks guys, the crux of what im getting at is this. Say theres 120v between line and neutral, this potential difference causes current to flow, normally back to the supply transformer through the neutral (which is at earth potential 0V). Okay I get that. So in a live system there is current flowing through the neutral right, so why do i not get a shock if im standing on the ground and i touch the neutral, because there is still current going through it isnt there !!

I suspect it has something to do with the fact that there is no potential difference between the neutral and earth (that im connected to via the ground in this instance); so in that case there is no voltage between neutral and earth, but there is current flowing through the neutral from the live 120v. But i cant feel this 120v if i touch the neutral while im standing on the ground !!! WHY IS THIS PLEASE HELP

the neutral is usually already connected to the earth by the utility providers.

Physics, Astronomy & Cosmology / Re: How are muons detected and generated?

« on: 24/11/2017 01:18:13 »

I found an interesting video describing muon detection to demonstrate time dilation.

This is the most comprehensive material I've ever found. But I have some questions need to be cleared.
How to make first spike which represent the event of entering muon into the scintillator always occur on the left most side of the oscilloscope display?
How to determine that other factors that can influence the reading are negligible, especially the possibility that new muon is created between top mountain level and sea level?

Physics, Astronomy & Cosmology / Re: Is the photon model of electromagnetic wave an oversimplification?

« on: 21/11/2017 04:20:22 »

Many strangeness in results of experiments showing single photon detection that we found in popular science news hide complexities faced by experimenters. We can even find some papers published in scientific journal depicting a single photon going through complicated macroscopic device such as beam splitter and prism, and stays as single photon on detector.

Referring to photomultiplier tubes handbook from Hamamatsu Photonics, we find that single photon detection is not as simple as depicted in popular documentary movies. In my opinion, the existence of dark current and thermionic emission reduce credibility of single photon detection. Instead, they show electron detections from earlier stages of the dynode.

Physics, Astronomy & Cosmology / Re: How are the results of the double slit experiment recorded?

« on: 03/07/2017 12:40:46 »

If we assume that light is stream of particles, just like Newton did, the occurence of light and dark bands on the screen is an unexpected result.
If we assume that light is a wave, akin to wave of water surface, then the unexpected result will show when the intensity is extremely low,  undetected by naked eye, hence requires very sensitive sensor, such as photomultiplier.

Physics, Astronomy & Cosmology / What is the effect on the moon's orbit of harvesting tidal energy?

« on: 19/05/2017 10:32:29 »

Harvesting energy from tides is known to make the Earth to rotate slower, but what is the effect on the moon's orbit? Measurements shows that the moon is moving away from Earth, but that means its potential energy is increasing?

General Science / Re: What is the science behind the Brocken spectre phenomenon?

« on: 29/08/2016 11:48:12 »

There's got to be refraction too, to split the white light into the constituent wavelengths.

So what's producing this?

Diffraction.
With refraction, as in a rainbow, longer wavelengths are refracted more than shorter so the red is on the outside of the bow.
With diffraction it's the other way round, shorter wavelengths are diffracted more and so blue/Violet are on the outside of the rings.

Correction:
longer wavelengths are refracted less than shorter so the red is on the outside of the bow.
shorter wavelengths are diffracted less and so blue/Violet are on the outside of the rings.


Comparison of the spectra obtained from a diffraction grating by diffraction (1), and a prism by refraction (2). Longer wavelengths (red) are diffracted more, but refracted less than shorter wavelengths (violet).

General Science / Re: What constitutes evidence?

« on: 11/08/2016 02:46:52 »

That formula does not actually give exacting answers in the particle oriented universe. You might make a good general guesstimate using it, however you will find that different results occur, at different distances. Because of the way rays at a certain velocity are altered as they pass through matter. It is a variable that E=MC^2 does not even consider.

So many modern scientists and schools teach that you can stop radiation with materials. They say you can stop infrared, light, or x-rays with materials. However if you actually do some hands on research you will find that the radiations are positively accelerated, to velocities that we no longer detect as the original radiation. Or, we are no longer negatively affected by the now normal ambient radiation velocity emissions, after they pass through a substance or structure.

Look at a radiometer, in the dark infrared will not spin the radiometer. With the faintest light present in the room the radiometer subjected to infrared will spin with amazing vigor, many times faster than direct sunlight or other light source. The reason is that the white paddle when illuminated by light allows a light emission to carry away the heat of the infrared as light instead of heat. However in a dark room both white and black paddles heat evenly under the infrared emission and the device will not spin. 

We used to harden metal with compounds that contained zinc and or phosphorous that would glow with a blinding light when a red hot piece of metal was placed into the white powdery substance. It would cause even soft hot rolled steel to obtain a hard surface hardening. By quickly removing heat from the part. More than cold water quenching. 

Sincerely,

William McCormick

It seems like an interesting experiment. Can you provide the link to articles or videos about it?

Where can we find your fractal equation?
What is the new information we could get from your model which currently accepted models don't provide?
Are there specific phenomena which can be described more accurately using your model, compared to currently accepted models?

Technology / Re: What force must the biceps develop to elevate the forearm against a given load?

« on: 03/07/2016 05:35:35 »

I am currently studying for a biomechanics test next week.  I've been given two weeks notice, and with no help from tutors (as they are all away on holiday  [] ) I have been left to my own devices.

I am not looking for the answer, only how to go about getting the answer for the attached question.

Sorry if this is trivial to most  []

Thanks in advance  []

 [ Invalid Attachment ]

For answering question a) you use the elbow as the axis of rotation, and assume that the upper arm is rigid so you can ignore torque components there.
For answering question b) you use the top of upper arm as the axis of rotation, and assume that the elbow rigidly attach lower arm to the upper arm. So you need to calculate all torque components there with top of the upper arm as reference to calculate the distance and angle of each force shown in the diagram.
