This achievement has earned you your "Golden One" Level 3 Badge!

WOW, that vacuum slowed down the bowling ball to the speed of a feather. Pretty cool. That's why nothing can go faster than the speed of light.

Its definitely relativity.

They fall at the same speed? As each other? With respect to what? Why are they even falling at all?

In relativity you always have a frame of reference. If you take the speed of feathers with respect to that of the bowling ball in a vacuum, the difference is zero....they aren't moving at all within the frame of reference.

No need to complicate things by bringing the earth into the equation.

Its a round about way of using something so simple to explain how relativistic equations are handled in his works.

They have a great example of this in the Exploratorium in SF, but in a rotating/flipping clear plastic tube with a feather and a plastic army man and a button to turn on the vacuum.

Yeah, those last couple sentences throw me for a loop also. I *think* he is referencing relativity, in that the objects are behaving relativistically towards each other, but if you remove/ignore the earth (and air) then you are missing one half of what they are "relative" to. Or that the Earth and the air are also (minutely) attracted towards the bowling ball and feather, or something.

Would definitely be nice to see the next few minutes of this show to see what he's eluding to...

Wait, I want to know what happens!

Why did Einstein say the ball and feather weren't accelerating toward earth?

If I didn't know better, that crow had a few people say that to him, and it just repeated as a greeting. I especially like how its feathers puff up when he says it.

That said, crows are supposed to be quite intelligent.

Eh, it helps to view it on a real monitor, not a smart phone. It appears there are a lot of birds congregating up there, and a bunch died. Originally looked like one bird exploded with feathers everywhere, and the other flew away. Now it looks like each "feather" is actually a bird (minus the light fixture).

Am I the only one who feels a sadness for the birds?

Not only do i think this is wrong, but i think it is obviously and patently wrong.

It is demonstrable that a confrontation does not necessarily escalate the longer it goes on for. If you've been taught that in training by someone purporting to be an expert then i despair. I almost feel at a loss for where to begin - i have been in thousands of confrontations that de-escalated due to more time passing allowing both parties to explain or understand better, or for the blood to cool down. I've seen thousands of the same types of confrontation happening to other people. It literally happens all the time; misunderstandings get corrected and the situation de-escalates.

I hope that the brief explanation has betrayed what you really meant. Perhaps you were talking about a specific range of situations with a violent individual.

Or perhaps that's the problem and someone has been training law enforcement this falsehood which effectively encourages you to use the most extreme measure you have to end the conflict more quickly and keep it at a safely low level of escalation. And then you end up with mine- and rocket-resistant urban combat vehicles patrolling the streets, teams of camo'd police holding weapons INCORRECTLY in the presence of civilians on your own streets, and the mowing down of unarmed shoplifters...... all because it's more kind that way? I refute that, and before anyone says the most dangerous words ever spoken 'but we've always done it that way', in a discussion about the ineptitude or otherwise of law enforcement you aren't allowed the premise "law enforcement's methods are and always have been the best way to do things." -- Law enforcement, along with politics, should be the most heavily scrutinised and re-scrutinised systems that exist - because of their unique position to affect people.

I do NOT consider the concern for the safety of a police officer to be greater than the concern for the rights of a citizen; i was under the impression that police were the defence line between citizens and criminals, they put their lives on the line to keep society safe and running. Their job is to ensure we can be citizens, and they are paid to uphold the ideals of the society - freedom, respect for the individual and personal security. I genuinely hope they do so safely, but you don't play with feathers unless you're willing to get your arse tickled, as the saying goes. It is very possible to be safe, respectful and understanding all at the same time in the pursuit of law enforcement. If a person does not have the ability to behave that way they should not be in the job in the same way as someone who finds kids irritating and hit-able shouldn't go into childcare.

No dude, you're just getting started being called to the mat and you slinkety-slink the fuck away??? You orchestrated your own demise on this one, Sir Done.

-Callin' real-time-jewels of Papier-mâché on a comment as flaccid as the sack there sagging and displaying their feather-like weight....Faced with truth, the sophist...(deliberately obtuse at times and otherwise generally hostile) has but the tinny-sounding bell-tinkle heralding a hasty departure, as a familiar a fanfare as a copper's si-reen :0

dOUCHE + a bag = a lady's freshen-up.
Please....Show all the ladies how it's done again??

Those dino-suit/robots are f'ing cool. I'd love to see one IRL. Glad to see it's feathered too. Folks are finally starting to accept that fact after so many years of them looking like lizards.

Actually, they just didn't want their bad ass smart dinos named "Achillobators" and thought Velociraptor was "more cool".

Otherwise, the JP "velociraptors" were somewhat accurate except for their lack of feathers.

...and judging by the head, the baseball dino is a baby TRex.

Isn't this a Raptor, not a T-Rex ?
also, kudos to the creators of the costume for adding feathers!

You're justifying your inability to spend time with people of other races because of "shared experiences" with other white people? Buuuuuuuull-shiiiiiiiiiit. I've found that I have common ground with just about anyone in the world, just involves me trying to be a good human being and not being afraid of disagreeing or having conversation with people of differing view points. Most of my friends are worlds apart and it doesn't matter. Birds of a feather -- die together. (Whoa, that was way more ominous than intended.)

But I do agree, the banning, and fining of Donald Sterling is akin to punishing someone for thought crime. I don't understand how a comment made in private could be used in such a way. I don't agree with his racist views, or in your justified segregation, but I don't think it's a wise decision, nor a justified one, to punish anyone for having such views or even for expressing them in public, let alone private.

If you don't like someone's you have the right to ignore them and to NOT give them your money, and to convince others to shun that person. But that should NOT givbe any institution the right to go after anything in your estate.

Our justice system is a sham of personal opinion blurred into pseudo civil rights.

Anyway, people shouldn't be afraid to express their views, even if it's offensive to others.

Being stuck between political correct asshats AND conservative christian fuckbags is the real crime -- and I should be able to collect money from racist bigots AND the NAACP. (Just kidding.)
