Does significant different mean big difference....to me it looks like hydrogen has a significant difference with carbon...meaning carbon is all the way to the right and H is to the left

My English is not that good especially in listening, so subtitles could be very helpful for me.

Very good. A lot to throw out there in the first lecture. You might scare a few off, but very good.

Every time I take a break, I am unable to fast forward. This is very time consuming. Is there anyway I can fast forward without waiting for a buffer?
