Brady, are you planning to do an 'any questions' series like you did with 60 Symbols?

[periodicvideos]

@slartibartfarst Hi, I'm sure we'll do it at some stage... Between elements, molecules and the new chem definitions... we already have some Q and A videos with school students, but we'll do it with the YouTubers in the near future!

whoa! i learn a lot from this video, thanks. so interesting... whoaa! gold in purple..cool!

[periodicvideos]

@vhiechava glad you liked it!

[mvszao]

I knew the purple one was made of gold. I don't know why, but I'm sure I've learnt watching periodic table of videos

[periodicvideos]

@mvszao yes, out video called "Extra Bits of Gold" showed red nanoparticles! I''ll post it here as a video response.

I am very honoured that you have made a video about my display. The size of the gold and silver nanoparticles are about 13 nm in diameter and each nanoparticle is made of many (more than 500000) atoms.

@andycapo123 well thanks again for sending it... very cool!

Brady, when are they going to let you tape lectures and classes. Even if the cam is mounted on the back wall. (less work). You guys are fully aware that many an inquiring mind could never afford University at any level. Hope to see it someday. Thanks for everything so far.

If you had a very large amount of Gold, would it appear blue?

[eltotoX]

DUDE I've had that question in my mind for so long. I knew the colour would change :D

Whos in charge of the youtube channel and the one who makes the comments? for some reason, I always thought it was pete.

[nirvana9610]

how to make 13 nm in diameter particles?

[Furiouslyfappin]

@anticorncob6 Energy in the sense of electricity or in the broader sense of energy as a force? In electricity it is the free flow of electrons. However as a force, that's a little more complicated question. If you know Einstein was the first to say that energy and mass are the thing in different manifestations, mass is energy. Without an understanding of mass-energy equivalence it doesn't make much sense. Go to sixty symbols!

twenty not 2000!!! (twenty-eleven)

!!! Marie Curie looks a little like Abigail Breslin might in a couple decades heeheehee

@satan31337 You go like this:

1)atoms 2)protons, neutrons  3)electrons and quarks 4)strings (if string-theory is correct)

Light and sound are not made up of ions, protons, and neutrons (ions are just atoms with a different number of electrons; you're saying energy is matter). In case you didn't realize, I didn't ask what atoms were made of, I was asking what ENERGY is made of.
