Hi

compiled languages are useful for professionals or people caring about performance. Interpreted ones are easier to get into.

For you, I would recommend Python 3. This is a interpreted script language very user friendly, very portable, with lots of libraries (graphical, network, scientific calculation, etc.). With it, you can do quite everything you can imagine (desktop or mobile apps, even back-end web servers can use python).

however, is you wish to do your own website, you'd rather have to get into (in this order) HTML 5, CSS 3, javascript, jQuery and bootstrap for the front-end, and then, for the back-end, learn about databases (mySQL, etc.) and back-end language (php, Node.JS, etc.) to start with. When you have an idea of all these language can do, you will be able to have fun with your high quality website.

Hi,

you can try this playlist :

All his explanations are crystal clear. Short videos, easy to jump to your topic. The best css playlist I know...

E=mc² is a formula figured out from the special relativity which is one of the most beautiful discovers of the 20th century. This theory is now accepted as the main framework for all phisics theories like mecanics, electromagnetism, particule physics, etc. Thus, nowadays, if a theory is not relativistic, no theoretical physicist will want to ever think about it.

E=mc² is only the surface of the iceberg, it "just" tells that there is an equivalence between mass and energy, which means that from empty space, a particule can be spontaneusly created provided that enough energy is located in the "same space", leading to quantum fluctuation.

Regarding the nuclear bomb, I will just ask a simple question :

Do you think that the first guy who discovered how to make a fire should be ashamed because of flamethrowers

Hi boba,

atmospheric pression at low altitude (sea level) is a huge force per area (~ 1 Kg / cm²). So, even if molecules have a big energy (thanks to ambiant temperature), they are not powerful enough to fight against this force. But when pression vanishes, ambiant temperature is large enought to make molecules leave the little pot and get vaporized. It is the same phenomenon that explains why water boils at less than 100°C (212 °F) in the mountains or in any low pressure spaces.

Some molecules keep connexions with their neighboors and finally encompass some air, creating bubbles. We can guess that gel molecules are something like "amphiphilic" like soap, which means that they have one side of the molecule which is hydrophilic and the other which is hydrophobic and thus being able to create a thin surface that will enclose air.
