Teaching You Chemistry 1

Teaching You Chemistry

I am currently studying Chemistry at A-Levels and I wish to share what I learn with you, after all it is said that teaching other people is a good way of revising, so it benefits both me and you. I will start with the basics and work up from there.

The Atom

Atoms are what all elements and compounds are made out of, they are very small and cannot be seen with the naked eye. Atoms are made up of 3 types of particles which are the protons, neutrons and electrons, the proton and neutron make the nucleus of an atom.

Electrons:

Electrons have a -1 (negative) charge and the whizz around the nucleus in orbitals (circles), these orbitals make if for most of the volume of the atom.

Nucleus:

The majority of the mass of the atom is concentrated in the nucleus. The diameter of the nucleus rather small compared to the whole atom, inside the nucleus is where you can find protons and neutrons. 

Protons have a relative mass of 1 and a relative charge of +1

Neutrons have a relative mass of 1 and a relative charge of 0 (no charge)

Nuclear Symbols show numbers of Subatomic Particals

The mass number tells you the number of protons and neutrons that are in the nucleus,

The atomic or proton number tells you the number of protons in the nucleus

You can work out he number of neutrons in the nucleus by taking away the mass number from the atomic number (mass number-atomic number= neutron number). In this case 4-2=2, the neutron number is 2.

Why does time seem to fly by as we get older?

Why does time seem to fly by as we get older?

When you think back to your childhood or adolescent years, time seemed to pass a lot more slower than it does now, but why? Why did say, the first 10 years of our life seem so long while going from ages 30 to 40 seem to happen so quickly? Well people have looked into this, they managed to come to the conclusion. When you're 1 year old, that 1 year has been 100% of your life, when you've reached your 2nd birthday that year was a half of your life, when you're 3 years old that year was 1/3 of your life and when you're 40 years old 1 year is only 1/40 of your life, so it could be said that you become kind of adapted, but you could say that theory isn't very reliable. However, when something novel, something great or big happens in your life you tend to remember it, and as you look back on memories, you change something, its the reason why two different witnesses can give different feedbacks about a crime they saw being committed (not taking the fact that one is lying into account). It's been found that when something big happens in your life, like your first kiss. When you think back upon these memories within your first 10 years it feels longer because there's so much more to remember. So this means the more you do with your life, the more people you meet, the more places you see, generally the more big and exciting things you do in your life, the slower time will seem to pass, so get out there and live your life!

Should you walk or run in the rain?

Should you walk or run in the rain?

Say it's a rainy day and you want to stay as dry as possible, should you walk in the rain or run in the rain? Walking in the rain would mean that you are travelling slower to your destination, meaning that more rain drops will hit you, so you should run, right? However running in the rain basically means you're just running into the rain anyway, you're not escaping any rain. If you move out of the way of one rain drop, you move into the way of another, so the number of rain drops hitting you is constant no matter your speed. If you don't understand this properly let me explain this better, if you think of rain as something that stays still in the air, it doesn't matter if you walk into that rain or run into that rain, you're still getting into it. If you don't actually go anywhere, and stay still, you will be drier than if you run/walk because rain is only hitting you from the top while if you walk or run rain is also hitting you from the side. Now there's the time factor, if you want to get to one point to another then the time factor comes into play, its a known fact that the longer you stay in the rain, the wetter you will get. Walking in the rain and running in the rain does mean you will get the same amount of rain drops on you, however the longer you stay in the rain, the wetter you get, therefore running will decrease the amount of time in the rain thus meaning less raindrops than walking.

TLDR? RUN IN THE RAIN

Multiverse Theory

Multiverse Theory

Before reading note that I'm try to simplify what I say so that any reader can understand, this in turn may cause some of my information to be a scientifically incorrect, but still along the right lines. If you want to learn more then I suggest you go into deeper research.

The Multiverse Theory is the theory that we are not the only universe. It's the theory that there are many more universes other than ours, which are unimaginably different. These universes may not have to apply to the laws of physics. This basically means that each universe has to follow these rules, but except for that each universe will be unique in its own way. The multiverse theory has been discussed before in the following fields: cosmology, physics,astronomy, religion, philosophy, transpersonal psychology and fiction,  mainly in science fiction and fantasy, basically meaning it isn't a new theory. Multiverse theory was coined by American philosopher and psychologist William James in 1985.

The Multiverse Theory also can also be tied into what is called the Bubble Theory. This is the theory that each universe within the multiverse is inside its own "bubble". The Bubble Theory explains why its highly likely that us as a human race will never be able to go into another universe within the Multiverse. The Bubble Theory states that between each universe there is a gap where nothing can exist meaning that we can not physically leave our own universe or "Bubble". However I say its highly unlikely for this reason, if somehow we manage to get the right technology, we can create a point so hot within our own universe that it will cause a bubble come out of our own universe, this will create a completely new universe. When this new bubble is formed there is a very small amount of time (probably smaller than milliseconds) where there is a kind of bridge between the our bubble and the new bubble, if we can travel that fast through this "bridge" then we will be in this new universe we just created. There will be no way for us to go back into our previous universe. We will be the "Gods" or creators of this new said universe.

This is what it will look like when
creating a new universe (I guess).
