 Hello!  Heat - Heat is an energy that is transferred from one body to another because of a difference in temperature. Heat flows from hot bodies to cold bodies ("bodies" meaning objects or matter). Hear energy is created when aroms move faster and collidep. It is also known as thermal energy, and heat is the transfer of said energy. Light - Light is a kind of radiation that can be perceived by the human eye. It has wavelengths which can differ, forming what we know as colors. It can travel, refract, reflect, diffract, interfere, and disperse, etc. These things is possible by light.

 Hello! Today is about matter and energy, and the second week of the Physics series. What is Matter? Matter is a physical substance which occupies space and has mass, distinct from energy. Matter is physical, so it does not have a rational nor conscious nature, at least itself. The popular understanding is that there are three states of matter, which is true, though there are other things considered as states of matters, the most popular of which being plasma. Basically, matter is a physical object. But it says "distinct from energy". What is energy, then? What is Energy? Simply, energy is a capacity to do something, especially moving something else. Energy falls into two central categories: kinetic energy and potential energy. What is the difference between the two types? Kinetic energy is in movement, while potential energy is not used, but usable to work.

 This is the second week of our ScienceForDummies new format and we are entering a 4-term period where we discuss particularly physics. This week will just be an introduction on the question "what is physics?". the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity,  magnetism , and the structure of  atoms . That is the standardized definition of the word "Physics". Let's break the paragraph-long definition down and explain it. "the branch of science" is fairly practical - basically a kind of science. "concerned"  can mean "relating to" and "about". "with the nature and properties" means it is about how something is - its nature - and its particular features - its properties. "of matter and energy" means about matter - whic...

 Hello! Today we will begin our new seasonal formst of ScienceForDummies by doing an introduction of science itself. What is science? Well, according to the Oxford Dictionary, it is... 1.  the systematic study of the structure and behavior of the physical and natural world through observation, experimentation , and the testing of theories against the evidence obtained. Let's cut that definition down. First, "the systematic study". What does "systematic" mean? Systematic means it is intricate, planned, and carefully done, rather than done with no form of flow or process. "Study" means subject or topic in this case. Next, "of the structure and behavior of the physical and natural world". This sentence is slightly more straightforward. This intricate and planned topic is about how the physical (relating to space (space being the dimension and not outer space)) and natural (relating to what is not done by humans) world works and behaves ("be...

 Hello!  Currently I'm just recycling past ideas, so my new concept for ScienceForDummies is a serial concept. I'll use this week just to plan, but here's the new idea: For the next few weeks, I will cover only one part of science (e.g physics, biology) and do it in a more deeper fashion rather than simply answering a question. After a few weeks, I'll switch to another one. I think from 24 November until 15 December - 4 Sundays - I will cover Physics first. In 17 December, I will do a science theme where I explain, "what really is science?".

 Hello! I'm currently recycling ideas from the past. The next idea is about rabies, a viral infection that is nearly 100% fatal. It is among the most fatal diseases to ever contract. But how does it work?  Rabies is transmitted through noth humans and animals. Let's see what it does to someone's body. The virus that causes the disease is a lyssavirus. Lyssaviruses spread through saliva of  animals. The animals that usually transmit their rabies filled saliva are dogs, raccoons, bats, and foxes. It has other causes but mosr of the time, however, it comes from animal bites. Lyssa means "rage" which will make sense soon. The virus is neurotropic and aims to reach the brain/the nervous system. Once it gets into your body, it automatically prepares to enter the brain. Immune cells are blind to the rabies virus because this virus multiplies slowly and steadily. Once it reached the brain, it is almost always over for the thing it is infecting. The immune cells could not ...
