flu and school

It is surprising how fast things change. At math class today, everyone was gloomy about how school was going to drag on, and how we have to make that one case to shut down the school. We then tried to comfort ourselves by stating that maybe it wasn't so bad to be in school after all.

I slept on a desk for more than 3 hours, dreaming thermodynamics, thinking how i was going to do that experiment next week in chemistry. I actually managed to dream up 4 types of calorimeters, two of which I disappointingly found out have been patented because some chemist 300 years ago had struggled to find a better way to measure the energy of chemical reactions.

I woke up at 19:00 to get dinner and the tv said someone from South Island School was on the positive side.
Now I don't know what to do, because I didn't have any plans except for homework for the rest of the term.

Now, how do I hand in my english essay?

The thing about thermodynamics

Stuff can never actually "stop", because another process is necessary to intervene. That process may simply take the energy out, but then you increase the entropy elsewhere, so system still has or increased the disorder.
If you wanted to reverse a process, you must stop it first because it is going one way. The laws don't change in reverse, but they have continue doing what they do unless you stop them.

The interesting thing about thermodynamics is that thermodynamics has to do with all the changes and differences in heat energy and work. 

It takes a difference in heat to make a heat engine. Hence, according to thermodynamics, there is no way of extracting work from a reservoir(s) with no temperature difference. 

0-point energy is the lowest energy quantifiable or simply the energy remaining after all possible energy is taken away. This stuff means interesting effects when things are very near absolute zero, because they still possess some energy.
This energy is also supposedly in the vacuum.

I think this is interesting because whereas I have not found a device of this kind that has worked properly, the theory is there and it is scientific.

paper

I could have probably written a much better topic - 

Are grenouille in Perfume and Noboru in Sailor evil?

disagreement.

It was interesting to watch a disagreement between Alex Yau and Ms Stringer on some new Chemistry topic. Even when the consensus was following the rules, some still chose to side with Alex. I decided to check the textbook and he was not correct. Yet, people continued to support the incorrect. 

I think they will be thoroughly confused when they do homework.
