Complementary Medicine / Re: Is there a natrual treatment for athlete’s foot?

« on: 08/01/2021 03:43:54 »

Hi, there are many over the counter remedies for athlete's foot available. I heard for that rubbing tea tree oil is good for reducing athlete foot's symptomps because of its antifungal and antibacterial properties (should be mixed with a carrier oil, like coconut oil, otherwise it will sting). For crusty foot I found generally sea salt bath good as remedies. But I would maybe inform myself more about this or consult a doctor before trying any of this.

Essentially, what you have there is a  nice example of what's sometimes called "The canals on Mars effect"

There are no canals on Mars.
But with a fuzzy picture through a primitive telescope, your brain takes the limited information available and tries to fit it to some sort of pattern. The problem is that the brain does this, even when there is no pattern there.

Much of the time, this is a valuable skill- because we seldom have perfect information, but we need to be able to work out wat is going on in the world. And we live in a world where things often follow patterns.

Sometimes it goes wrong and we see patterns that are not there.

The commonest of these is that we see things happening which we do not understand.
Often, when we see things happening  it is because someone (or some animal) is making them happen.
So, when we see something we wonder if some "invisible" someone is responsible for making it happen.
Obviously, the "invisible someone" is mysterious and powerful.

Did you ever wonder where God came from?
Well, perhaps  you now know.

New Theories / Re: My Ideas for New Scientific Theories-What do YOU Think?

« on: 14/12/2020 12:25:43 »

I have presented my presentation to my form class this week! All went well, and it as a good experience, even if half of them weren't listening. Unfortunately, I could not video it, but I will attach a copy of the PowerPoint below.

Looking at your presentation, a couple of suggestions:
“How it happened”
(Psychoacoustics and neuroscience)

“Example 1”
In this and some other slides the picture forces the text to start bottom left, it would scan better if the text started upper left. That helps people who are used to reading left to right read your slide faster as it comes up on screen.

You ask about the speed of nerve impulses, you might start with something like this http://www.biologymad.com/nervoussystem/nerveimpulses.htm
Remember that we are also dependant on our brain’s interpretation of these impulses. Have you noticed that when we encounter something new - a new song, a new lesson topic, new story, a new skill, etc - time seems to pass much more slowly; people also mention that time slows down during an accident. This also happens when we are bored, with little stimulation.
Is this change of nerve impulses or a change in the way the brain is processing, perhaps putting all attention onto one thing rather than multitasking?
Might be worth exploring.

New Theories / Re: Could this be a new way to prove dark matter?

« on: 28/11/2020 19:49:43 »

The problem here is that dark matter doesn't "stick" to ordinary matter. It passes through it even more easily than neutrinos do. So it wouldn't change the weight of your squares. As far as we can tell so far, dark matter only interacts with ordinary matter through gravitational forces (which are practically non-existent on the level of individual particles).

I like your spirit, though. You remind me a lot of myself when I was your age. Keep on thinking and studying. You'll find many surprises along the way!

Chemistry / Re: Can reactions that use oxygen also use Nitrogen?

« on: 07/11/2020 00:02:02 »

It might be a good idea to explain just why Nitrogen is as non-reactive as it is.  Like oxygen, gaseous Nitrogen forms diatomic molecules, where two nitrogen atoms bond together.   Each Nitrogen atom has 5 electrons in its outer shell, so in order for each atom to feel like it has a full 8 electrons in its outer shell, each atom share 3 electrons with the other. ( 6 total are shared between the two atoms)
Oxygen does the same type of sharing, but since each atom has 6 electrons in its outer shell the atoms only share 2 electrons each ( four total).
Each pair of electrons makes up a bond. 
So the Oxygen molecule has two bonds and the Nitrogen molecule 3 bonds.
In order for either to participate in a reaction with another element, these bonds have to be broken first.
Three bonds are stronger than two, so it is harder to pull the nitrogen atoms apart in order to take part in a reaction.
This makes the Nitrogen molecule more stable and be less reactive.

Chemistry / Re: Can reactions that use oxygen also use Nitrogen?

« on: 06/11/2020 08:32:51 »

A few metals will react directly with nitrogen. The best known is probably magnesium.
Burning magnesium is a well known science experiment.
What's less well known is that it you collect the ashes and add a little water you can smell the ammonia produced when the magnesium nitride reacts with water.

Chemistry / Re: Can reactions that use oxygen also use Nitrogen?

« on: 06/11/2020 05:54:03 »

Although oxygen and nitrogen are right next to each other on the periodic table, they have very different properties. Oxygen is a powerful oxidizing agent and readily reacts with a wide variety of other elements. Nitrogen, by contrast, is a highly stable molecule and needs to be prodded in order to react with most other elements. Metal nitrides are usually much less stable than metal oxides.

Physics, Astronomy & Cosmology / Re: What are “ Higgs boson” particals?

« on: 02/11/2020 02:13:48 »

Essentially, the Higgs quantum field is a significant ingredient in the standard model of physics, a field which is responsible for mass, and all fields in QM have a particle associated with them. Hence the Higgs boson.

Yes, photons have mass, but not proper mass, and the Higgs boson gives proper mass (inertia) to things, which is part of what makes it take force to accelerate something.

Physics, Astronomy & Cosmology / Re: What are “ Higgs boson” particals?

« on: 02/11/2020 01:53:23 »

There should be plenty of information about it here: https://en.wikipedia.org/wiki/Higgs_boson

The interaction between the Higgs particle and other fundamental particles is responsible for giving them their rest mass. The Higgs also interacts with other Higgs in order to give them their own rest mass. Not all mass comes from the Higgs, however. Photons technically have a mass associated with their kinetic energy even though the Higgs does not interact with them.

New Theories / Re: My Ideas on New Scientific Processes In Our Bodies - What Do You Think?

« on: 31/10/2020 08:44:57 »

I did not know that the start and the end are classed as two different events.

In common English usage we talk about events, like Glastonbury, having a duration. In physics we describe events as specific points in spacetime.
So if we describe something which has a duration, eg the sound of a guitar string being plucked, we can describe the start as an event and the end as an event, but we can also define an infinite number of events between those 2. For example, if we take a point in space 1m in front of the centre of the soundhole and perpendicular to the soundboard, we can measure the point in time (at that point in space) when the sound has fallen 5dB; that would be an event.

I have also lernt that the body delays the sound and light so that we van hear them simultaneously. The futher the distance, the further the gap. This is why we see others’ lips moving at the same time as the sound being produced.

If my memory serves me correctly, I think this works up to about 10m, beyond that you notice the difference.

Sometimes, you might not be able to hear your alarm even if it is loud: you won't notice it for some tome. Can you explain why.

My guess would be that it has to do with the stages of sleep and the depth of each stage. There is sometimes the odd effect of the sound being incorporated into a waking dream.
The level of sound required to wake you is called the auditory arousal threshold, you will probably find info on the net. I think the fire services have done research into smoke alarm levels.

By the way, some of your questions could be asked in the main sections of the forum, as long as you don’t advertise your hypotheses.

One comment on your paper. Good start, but don’t be disappointed if you find the questions have already been answered. The important thing is to look at how they were answered, what procedures or experiments were used to determine the conclusions. Ask yourself what experiments you could set up, or what evidence you could gather to test your ideas. Enjoy.

Physics, Astronomy & Cosmology / Re: How can you tell the age of bricks?

« on: 29/10/2020 17:27:10 »

Hello,
All of you forgot to mention one of the most common methods most scientists/archaeologists use; Carbon dating(or radiocarbon dating.) They use it for fossils and ruins millions of years old but I a  not sure if it work =s for more recently produced artefacts.
Yours sincerely,
Salik Imran.

Radiocarbon dating only works well for things that were alive.That excludes bricks.
It also only works for items younger than about 60,000 or 70,000 years old.

New Theories / Re: My Ideas on New Scientific Processes In Our Bodies - What Do You Think?

« on: 28/10/2020 23:36:54 »

I have been recently been having ideas about the physics that occur in our bodies and I have come up with a few theories.

Looking at your pdf:
“I think that the point when the action is created is ‘ground zero’ and might
be faster than light as it takes up no time. It’s hard to explain but I think
you get the idea. Of course, this might not be the case for events that take
a long time to start (not end) but it can be the case for the starting point
for a chain of events that take quite some time.”

The event might be instantaneous, but it won’t be faster than light unless it is travelling somewhere. When information about that event is travelling the speed will depend on how it is travelling eg as sound or light.
Yes, some things can take a long time from start to finish, but we would usually count the start and finish as separate events, each with their own positions in space and time.

“Could there be a connection between heart rate, blood supply and nerves
that can have an impact on the speed of the nerve impulses? Could your
emotions or state of mind have an impact too?”

The emotions and state of mind control hormones which certainly have an effect on heart rate, blood supply etc.
It appears that our perception of time is more to do with the brain’s interpretation than speed of nerve impulses. See this article on an experiment to investigate this https://kids.frontiersin.org/article/10.3389/frym.2017.00032
 
“When you sleep early, your family are still downstairs and are talking
loudly. You can hear every whisper, quiet click and shout from the noisy
room. But the people downstairs can only hear themselves. You want to
grab that midnight snack from the draw on the other side of the room.
You get up and you are worried that your family can hear you as you think
your breathing is loud and that the floor is too creaky. THUMP!! You
knock over your lamp and panic that your parents have heard you over
their talking but what you do not know is that they did not hear you; why
is this?”

Yes, our hearing is much more sensitive when we are lying down or asleep. I found this out when I first set a clock radio. I set it at a level I thought would just wake me, so fairly quiet. The next morning I woke with a start to what seemed a very loud radio.
There are a number of factors involved in why your parents don’t hear you. The most obvious is that the sound level has decreased by the time it reaches them. As you say, the background noise where they are will mask the sound of your thump - up to a point. The effect of one sound masking another is quite complex and depends on the relative levels and frequencies of the two sounds.

If you are interested in sound perception look up psychoacoustics, it is a fascinating subject.

Do keep researching and expanding on your ideas, you are making a good start.

New Theories / Re: If there was one Big Bang event, why not multiple big bangs?

In a universe that has always existed, as it has according to my ISU model, any reference to "stars in the earliest period of the universe" should use the words "in an earlier period of the universe", not "the earliest period". I'm proposing that in an eternal and infinite universe, time simply passes moment by moment in an orderly fashion.

In regards to what you say about hearing, I've learned from personal experience that the ears do adapt to local noise levels. I work in a loud facility and have to wear earplugs. One day, one of the plugs came out and I, somehow, did not notice until the end of the work day. When it was time for me to go home, I took the other plug out and discovered that my hearing in the plugged ear was much more sensitive than in the exposed ear.

Science Experiments / Re: Writing a strong Research Paper

« on: 16/01/2019 06:43:18 »

The best way to write a research paper is to do a background study of your research topic because the better you know about the topic the more you can write. Although the above-mentioned method is proper way to write and publish a research paper in the end, it all comes down to the content of the paper. The concreteness of your research paper is the main factor that can increase readability and authenticity. You can do this by adding references and solid facts and figures to your paper. Remember the quality of your paper matters, not the quantity.
