There Are Six 'Colours' Of Quark

Fact of the day: There are six 'colours' of quark.

Quantum Chromodynamics is the study of quarks and how they interact.
As far as we know, quarks are fundamental particles, this means that no other particles make up quarks.
There are six colours of quark (in quantum chromodynamics [chromo meaning colour] different types of quarks are called colours). There are the up quarks, the down quarks, the charm quarks, the strange quarks, the top quarks, and the bottom quarks. The up and down quarks make up protons and neutrons. There are also antimatter counterparts for all of these colours of quarks.


(above) The section of quarks on the Standard Model Of Elementary Particles.

Each quark has an electrical charge. The up, charm, and the top quarks (known as the up-type quarks) have an electrical charge of  + 2⁄3. The down, strange, and bottom quarks (down-type quarks) have an electrical charge of − 1⁄3. This is why protons have a positive charge (protons are made up of 2 up quarks and a down quark [+ 2⁄3++ 2⁄3+− 1⁄3=+1]), and neutrons have a neutral charge (they are made up of 2 down quarks and an up quark [− 1⁄3+− 1⁄3++ 2⁄3=0]).

Quarks are only one half of the types of matter in the Standard Model Of Elementary Particles, the other being leptons.

There Are Over 1,000,000,000,000,000,000,000 Atoms In A Drop Of Water

Fact of the day: There are over 1,000,000,000,000,000,000,000 (approx.) atoms in a drop of water. Particles. They are almost everything in the universe. From the computer that I am writing this with, to the light coming through my window from a star millions of lightyears away. They are made of particles. As I have briefly mentioned in one of my previous posts, particles have a wave property. This is called the wave-particle duality. Every particle has a wavelength. Even carbon 'buckyballs' (a molecule that is a ball of 60 carbon atoms) have been measured to have wavelengths. Apparently, a tennis ball has a wavelength between 10^-33 metres and 10^-35 metres (this must have been calculated, not measured). Despite the wave-particle duality, most different forms of matter and force carriers are classified by their particle type. All of the discovered fundamental particles (they cannot be split apart into new particles) are in the Standard Model Of Elementary Particles. I

The First Man Stepped On The Moon In 1969

Image
Fact of the day: The first man stepped on the moon in 1969*. The moon was formed at around the same time as the Earth, and some theories suggest that the moon formed when a mars sized planet collided with the Earth and the moon formed from the debris. The moon is the fifth largest natural satellite in the solar system, and the largest natural satellite in relation to its host planet. Most people think that the moon is really close to the earth, but the distance is actually around 4 times the diameter of the earth. (above) The Earth and the moon taken from Mars. The moon always shows the same face to Earth as its orbit and rotation are synchronised by coincidence. It takes around 29.53 days to orbit the Earth and rotate once on its axis. It has no atmosphere, and as a result is covered with impact craters. The moon's noticeable effect on the Earth is the tides, but has many other effects, even effecting the weather.

There Are 15 Types Of Energy

Image
Fact of the day: There are 15 types of energy. When someone says energy, most people think of electricity, or light. Energy is so much more than that. Energy takes so many forms that the definition is very simple and generic. Energy is the ability to do work. Energy can never be created or destroyed, but can be interchanged with matter ( E  = mc  2 ), so the overall amount of mass and energy in the universe remains constant. Energy can be changed between different types of energy. Types Of Energy Kinetic Energy Kinetic energy is basically the energy that an object uses to move. Potential Energy Potential energy is the energy 'stored' in an object in relation to its position. For example, when you pick a tennis ball up, the kinetic energy that you are using to pick the ball up turns into gravitational potential energy, and when you drop it, the gravitational potential energy then turns back into kinetic energy for the ball to drop. Mechanical Energy The sum of an o
