Physics – a natural science

The name “physics” came from Greek, meaning “nature”. Indeed, physics could explain the whole universe with its complicated string theory. To me, chemistry and biology are actually physics. At the end of the day, substances and all reactions are made of particles and the forces among them.

This is a talk by Professor Michio Kaku which could give anyone inspiration for the science

Bonus for anyone interested in string theory:

It would be amazing to think that the smallest particles are not particles but “dancing” filaments of energy. Different dancing patterns will give us different recipes to make particles, then we have different things in the world. Generally, things are energy and energy are things!

To me, the statement is so true because of two reasons:

– It is actually isomorphic with the formula E=mc2 by Einstein.

– The number of Dancing patterns is unlimited and that’s why scientists keep discovering lots of new particles.

And I have a couple of thinking:

– The Universe (in capital, meaning the universe that we are living in) is made of energy! Then is it possible that our Universe is just a dancing filaments in other universes?

– Dancing filaments make particles, is it true to say if they dont dance, they make “the dark energy”?

– What make them dance? (or easier, what can we do to change the dance patterns, so we will be able to transform particle)

– Do the filaments have anything to do with Higgs Boson?

You might have more questions than me after watching this talk by Bryan Greene

and Introduction of String theory by Michio Kaku:

P/S: non-matter “dark energy” is different to “dark matter”.

These are some assumptions about dark matter:

How we know that the universe is expanding:
