In this and then next article, I will discuss whether the past and future really exist and the practical implications. Indeed our perception indicate that only the present is real, but what happens to the past? Is it gone forever, or is it still real but unreachable, like a faraway star? And what about the future? Is it already there waiting for us, or does it get created as we move forward?Continue reading “Does past and future exists?”
This summer has been quite hot…So hot that I started to think how to turn off the sun for a while.. First thought would be to throw some water to the sun to cool it down. Will it work? After all, when you have a fire and you throw some water to it, it will cool down and eventually die off.. Can we do something similar with the Sun? Maybe throw a lot of water, like 10 time its mass to it? Continue reading “Throwing water to the Sun”
In the last article I explained what happen to uranium inside the nuclear reactors (I advise that you read that first). Now i want to close this topic with an article that explain what is usually happening to the nuclear wastes when they are removed from reactor. Continue reading “Spent Nuclear Fuel”
Yesterday I saw a commercial of Chernobyl HBO TV series and it inspired me to write this article on nuclear power reactors. The idea is to briefly explain the physics behind the nuclear fission and what happen to the uranium inside the reactor. So lets start. Continue reading “Nuclear Reactor’s fuel”
Yesterday I was playing with a Radon sensor. I got a little confused when I wanted to convert the dose from Becquerel /meter ^3 to Sievert, so this gave me the inspiration to write this small article on radiation types and measurement unit used to define them. Continue reading “Radiations and measurement units.”
So, This is the third article of the relativity series. It took me some time to write down because I was busy with other things and gave priority to the more technical articles. Furthermore I am not really sure that any of you is actually reading this stuffs… anyway, lets get started with some more basic concepts.
Today I will continue the discussion on general relativity that I introduced in my previous article on Inertial Frame of references. But this time i also want to illustrate the bigger plan that I have and the reason to publish this series of articles. Continue reading “Can you draw a straight line on a curved surface?”
Today I don’t want to talk about code, but about one of my other passions: Physics…I want to start this new thread with something relative basic: the concept of inertial frame of reference. In physics courses the importance of such concept is often underestimated by teachers. The concept of inertial frames is not only important in Newtonian Mechanics, but even more important in Einstein relativity. Continue reading “Inertial Frames in General Relativity”
