Just Chat! / Re: Is the extraordinary hot sunny and dry spring because of gods wrath at corona ?

« on: 10/09/2020 20:56:46 »

This is a really interesting question. Although I like to stay on the ground of facts and don't wonder about why this is happening to us. I also highly recommend reading this article about self diagnosing Corona so you know when you are a dangerous person for the people around you (https://www.medmeister.de/coronavirus-test/). It's in german but easily translated. But I honestly love the question.

Physiology & Medicine / Re: Does saliva have healing properties? Will licking a wound make it better?

« on: 28/06/2020 09:42:01 »

While licking your cuts and scrapes could theoretically help them heal, it’s a risky move. All in all, it’s best to stick to the safer alternatives: Soap, disinfectants and bandages. Not only is it more hygienic, it’s way less gross than slurping up your own blood.

Physiology & Medicine / Re: What is the evidence for scar-healing treatments?

« on: 28/06/2020 09:40:34 »

All silicone products work to reduce the size and overall appearance of the scar. It will often help heal discoloration and the texture of the scar. They contain antioxidants that make the scar heal more effectively. They heal skin by adding moisture, oxygen, and hydration. Sheets work faster because you can leave them on all day under clothing.  Sheets can be worn overnight too.

Silicone sheets reduce redness, and itchiness of the scar. They come in many sizes and can fit almost any size scar. It is the safest method around.  Silicone sheets, tape, and gel are an effective say to heal scars after surgery. How to heal scars is easy with silicone gel products. This is one of the most effective scar treatments with the least side effects. Ask your doctor to recommend a brand like scarheal to aid with your recovery after surgery.

Chemistry / Re: What is "Laughing gas"? Why does laughing gas make you laugh?

« on: 28/06/2020 09:36:47 »

Laughing gas isn’t all fun and games. When you inhale the gas, it displaces the air in your lungs and prevents oxygen from getting to your brain and blood. This deprivation is what causes all the giggles. Some people even experience mild hallucinations.

It takes about two minutes for the effects to wear off once you stop breathing in the nitrous oxide.

General Science / Re: How do they make semi-skimmed and skimmed milk?

« on: 28/06/2020 09:35:33 »

Greetings,

Skim Milk is made by removing the cream and the fat content, and, by watering down the ‘product.’ The object of “science” is to reduce the calories and the thickness of the product.

First, they harness cows into factory farms and then they shove their equipment up inside of them artificially inseminating them; it’s painful and intrusive. Their udders are so unnaturally swollen and milk laden for the millions of humans who somehow believe that they ‘need’ cow udder mucous?

They believe this because they were fed lies and corruption that “Milk does a body good!” When the calcium found in the mammary gland fluid of a bovine (cow), is not a fit for human calcium needs, nor, is the artificial chemicals, antibiotics and the pus generated from the pasteurization and homogenization processed which change the “fluid” into a sterilized white fluid that most people are used to consuming.

To make SKIMMED MILK, they remove the ‘cream’ that which supports life for the infant cow and they thin the “milk” with water making it contain less fat. Fat is what FEEDS YOUR BRAIN, the types of fat that are found in coconut flesh, avocados, nuts and seeds, real pumpkins, and many other foods that grow on the Earth and sustain you.

I genuinely hope this helps you~

General Science / Re: Why do colours add up together to make other colours?

« on: 28/06/2020 09:33:16 »

Color perception is a function of the cone receptors in our eyes. There are three distinct ranges of frequencies they are sensitive to (centered on red, green and blue). The actual determination of a "color" comes from our brain, taking the three values measured by the cones and representing that in our visual perception as a single color for that clusters of receptors.

Digital cameras work in the same way, measuring RGB frequencies of light and recording that as a single "color". Computer monitors display them in the same way, using RGB pixels to mix the light together and make our eyes see yellow, orange or whatever.

You can't mix frequencies we can't see and get "colors". All color perception requires our receptors to measure the light. A lack of light is just black to our eyes.

Physics, Astronomy & Cosmology / Re: How do materials make sounds when crumpled?

« on: 28/06/2020 09:31:20 »

Based on my own personal observations, it looks like it's caused by a process called snap-through-buckling. Doesn't look like Wikipedia has a decent explanation, so I'll try my best.

Snap-through-buckling is a process where a material deforms under a non-linear stress-strain curve. The best example is on your keyboard. If you have a modern keyboard, then you can feel snap-through-buckling for yourself. Notice how your keys don't really feel like just a spring on a button. It "clicks". That's because the series of springs under each key is designed to apply a different amount of force depending on how much you press down. The force will increase as you press down, but there's a point at which the applied force dips and causes you to fall through.

This similar behavior can be found on the tops of Snapple bottles. There's a little "button" on top that you can kinda click. It's supposed provide an indication about the internal pressure in the Snapple bottle. If it's too high, the cap will pop as opposed to gradually rising directly proportionally to the internal pressure. That's because of snap through buckling.

Now, my theory is that when you crumple paper, you create a bunch of 2-d planes that are unevenly folded in 3-d space. By applying additional force, some of these 2-d planes will pop open, like in snap through buckling.

When your paper gets wet and you let it dry, the water restructures the wood pulp that composes the paper making what would otherwise be a 2-d plane into an uneven 3-d surface.

Hope this helped!

The Environment / Re: Could vacuum cleaners be designed that would suck in locusts?

« on: 28/06/2020 09:25:56 »

No point using a bag cleaner of course, so I propose that a large cyclone device be designed, using eg oil-drums and fitted at the bottom with a fan powered by a small diesel engine. This would have a large inlet and be cheap enough for every farm to have one fitted to a trailer so as to be maneuverable into position beneath a swarm.

The bugs would be sucked into it in large numbers, probably coating the inside gradually with a layer of their carcasses. The majority would be deposited in a hopper (sorry) enabling it to be converted conveniently to animal food or fertiliser.

The Environment / Re: Wht causes swarms of locusts ?

« on: 28/06/2020 09:22:02 »

In the wild, swarms usually appear after a rainy period followed by a time of drought. After rains, populations of grasshoppers explode, because there is food aplenty. But when the land becomes parched and grass scarce, the populations get pushed into smaller and smaller areas, becoming more packed as desirable pasture diminishes. At a certain point of density, the swarm-inducing serotonin gets triggered and the locusts set off en masse to find greener pastures. After that, few things — other than an end to the food supply or an ocean — can stop them.

General Science / Re: The Start of Time?

« on: 28/06/2020 09:17:21 »

The question cannot be answered without answering another fundamental question: What is time? In short it is simply a function of distance which brings a more fundamental question: What is distance? Well distance is the measure of space relative to some arbitrary reference point with some arbitrary scale. I will try to explain things as simple as possible in the following discussion.

Imagine now the entire space to be composed of a discrete fine grid of lines just like some sort of knitting or fabric where energy and matter can only exist on those lines and not in between. So measuring distance is actually counting those lines or threads relative to some arbitrary starting point. Thus if we take the reference point to be some singularity that existed (many threads away) in the fabric then there will be no meaning for negative distance at all since we are only counting how many threads we are away from that singularity.

Of course sometimes the threads get pulled away or deformed due to gravity or acceleration. However measuring local distance is still counting threads so if we were only meant to exist on this fabric then we will never feel the difference that the distances between the fabric threads have changed. We can only know that those distances have changed by comparing them to other fabric threads in some distant points from the information carried with the light or energy coming from those distant points.

With this setup imagine that the number of threads is the only thing related to our space fabric that we can measure. So if we were travelling through this fabric or if this fabric was travelling through us at some speed then time will be the distance covered between counting one thread and the other. Therefore by definition it can only be positive and passing forward. If you come to think about it in this context, time has no meaning at all. It is simply the interval taken between the appearance of one thread and the next so it depends on speed, acceleration and deformation of the fabric.

Now let’s get back to the fundamental questions: Is this fabric limited or infinite in extent? Well at some point in the past many many threads back it was limited or at least much smaller. With the big bang the whole fabric stretched from one singularity and the distances between the compressed threads increased orders or magnitude in infinitesimal parts of the second.

Your question was when did the time begin? In our context we can put it as when did the first thread come along? Simply it came with the big bang. But what was before that or what was outside that infinitesimal singularity that formed the universe is the same as asking what is there between the threads of our current space fabric. Is it nothing as opposed to something? But what is nothing and does this nothing have any measurable properties? We know that energy, light, matter and time can only exist on the threads and not in between.

Our entire measurements exist only on the threads of the space fabric. The question of what’s in between is quite difficult to answer. We simply do not know and probably can never know. It is just like asking two dimensional beings that lived and existed entirely at the surface of a balloon what is inside your balloon?

Of course the above is not the only definition of time. There is another definition of time that is based on entropy. Entropy is a measure of the degree of randomness. Imagine a closed room and you break a bottle of red gas in one of its corners. At the begging there is some order in the room meaning that the red gas is in one place while the rest of the room is not affected by it so to some degree you can divide the atmosphere into particles belonging to red gas or outside the red gas. As the time passes the red gas spreads throughout the room increasing the randomness in its atmosphere. Simply we can no longer decide where each particle is. Thus, as time moves on, the degree of randomness increases and therefore entropy increases. This appears to be a fundamental law of our universe. We can thus define time by measuring the degree of randomness in the observable universe.

If you have a closed room or a closed finite system then the degree of randomness will always increase as the time passes by. But if the room is not closed and energy can be put to it then we can filter out the air in the room and restore order to its atmosphere. So entropy only decreases if the system is not closed or is infinite.

Simply if the universe is a closed system just like a bubble of matter and energy then this means the entropy of the universe is always increasing as time passes. Since the increase of entropy is related to change in momentum and energy of the macrostate, this means the macrostate of the universe thermal energy or temperature is always constant. However if the observed universe temperature is always cooling down then this means it is not a closed system. In other words it must be either infinite in extent or interacting with other universes where it can exchange energy. This may give you many ideas about what is really between the threads of our universe or space.

However, the idea of infinite universe or multiple universes exchanging energies is one theory and there are too many theories to count in one answer but they all remain theories and my guess we will never know what’s inside our balloon.
