Can we? get more lessons by John Lloyd
See: 6:20 “… electrons bumble down the wire, about the speed of spreading honey, they? say…” He clearly means electrons move quickly, but that the speed they are actually moving down the wire is the speed of honey.
Hmmm… Yes but he never said they bumble, just that they were bumblebees. Also the language constraints from the choice of words he used implies a direct comparison of speed and? nothing else. ie, He was not describing the motion path.
Actual not true? your bodies cells are not all replaced.
…….. Let me just clarify this first. If an object were moving really fast from it’s own perspective, but it were bouncing all around the tube down which it traveled and thus making slow progress, it could be said to be ‘bumbling’,? no?
Make sense, you do? not.
Hence why he said? they ‘bumble’…
Wondering why we’re here makes a couple important assumptions.
If we find how we came to be here maybe we’ll get some insight to the? question and if there is a why at all.
What are we going to do about it seems to depend largely on our own character.
At some level no one tells you who you are. You just are you.
When? a human spreads honey on toast.
Bees don’t spread honey.? They make it from pollen. Checkmate. 😉
He said “At the speed of spreading honey.”
As in, the speed at which bumblebees spread honey? Which can be of various interpretation and may or may? not be slow, much like electricity.
he’s a bit cocky isnt he? the? old basterd.
I am studying physics on a serious level. I’m at university doing an engineering degree. I agree about your comment on velocity. It’s not “magnitude and speed”. That was a typo. I later corrected it in a comment as “magnitude and direction”. I actually do understand, to some degree, how electrons move although I haven’t studied most academically and most models are quite difficult to explain to non scientists.
So how would you say they move??
Why do you comment about? stuff you clearly have no idea about? This is how misinformation spreads. If you haven’t studied physics, on a serious level, just shut up and don’t comment about how electrons move! You don’t even know what velocity is: it’s not “magnitude and speed” it is “speed and direction” and I’m not even going to begin to explain how wrong “The electrons are going near the speed of light” is.
this sh#ts pretty funny?
What is the name of the music used at the end of the? video?
Please tell me the pun was intended.?
How much did he pay that woman so she could loudly laugh? every 30 seconds?
@hxtieic for sure dude you hit the nail on the head there ALSO! this game? is tight been playing all day -> bit.ly/ZbRF8c?=rqoqp
I disagree. Language is strange. For instance, who gives it meaning? We do. All words are really just made up. We are their creators and only use. As such, we each give meaning to the words we, as individuals, use. Anything is true as long as the meaning I hold the words to is true. I could say “God exists” if, by God, I? meant my pet cat.
However, this skews the original meaning of language as a vessel for communication. So perhaps we should try to keep it concise.
No?
Very true?
Interesting?
And in that case? nor have any of the greatest thinkers that have ever existed.
Shakespeare, Chaucer, Keats, Darwin, Newton, Einstein, Wilde, Plato, Descartes.
They’re all rather useless…
Wrong on the basis? of technicality of word = Good enough.
