ScienceForDummies

 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 ...
