I think the X-1 is the first that could pass the speed of sound in normal level flight, without needing to dive to gain speed. That's my understanding at least. It ll depends how the record is stated though, it's almost certainly not the first manned craft to pass the sound barrier as you point out.

Except that you can't know all the properties of those atoms all at once. The Uncertainty Principle shows there is a fundamental limit to what we can know about particles. An exact replication would be impossible.

It's not the value of the safe that's important, it's the value of the contents. If you've only got stuff worth $173 you're probably not going to buy a safe worth that much to keep it in...

If you get a brand new rubics cube out of the packet there's no way a person could solve it in 5 seconds or whatever the world record is. The cubes used for speed solving are worn in, may have different tension springs in them and will certainly be lubed.

If human cubers can modify the basic cube then it seems fair that the robot cubers can too. I'm not sure there's anything in the actual rules that would prohibit a cube as in the video.

The humans also get a period of time to look at the cube and figure out the moves they need to do before starting. The robots don't get that. At the end of the video the robot figures out the moves and solves the cube in less than 1.1 seconds, without seeing it before hand.

Bonkers.

Where do they think the heat from the oven goes if you don't open the door?

I'm still struggling to believe that Trump is actually being taken seriously. People are so ready to hate.

WHAAAAT!!

Just a video of an arsehole abusing animals. I'd be surprised if they weren't defanged, or compromised in some way. He's making a show of being a shit head.

Awesome. It's amazing how close you can get to such a powerful wild animal.

In India and Africa the large game animals have learned to regard the vehicles in much the same way as they regard trees. they know they're there, they just don't bother with them in any way.

When we were in India on a tiger safari we had a very similar experience. The amazing thing was that people live and work in these forests. 100yds down the road from the situation in the video may be a party of women collecting firewood. Or one time we found a mahout looking for his elephant that had wandered off in the night!

Tigers are incredibly beautiful animals. they have a quality that sets them apart from lions and other big cats. They are so different in the wild to the animals you might see in zoos. If you've ever wanted to see what real natural beauty looks like then go and see the wild tigers, they're breathtaking.

So, which olympians do you think would be best at this? Rowers are brutally fit, as are the cyclists. Decathletes?

I would never use it, but I want it.

because they never see only of their shit applying to them, and everything is always someone else's fault.

Accidents happen with birth control (if you're even using it) but if you're a right wing religious nutjob then you're forced to bring your accident to term and into a life of shite because family planning isn't a real option.

No responsibility is taken. If the kids don't learn well at school then it's the teachers. Or the curriculum or whatever. It's bullshit. Teaching happens at home as much as at school, and I'm not just talking about homework.

My mother's just retired as a teacher in the UK. She'd have kids play up in class and end up having to phone the parents to tell them about it and discuss what they could do to help. Most of the time all she got from the parents was an incredulous 'what's it got to do with us? He's at school, he's your problem, if he's being naughty it's you who's fucked up'.

She taught kids who have never known anyone in their family have a job. Parents don't work, their parents don't work, and even their parents never had a proper job. These kids just don't understand their place in the world, or rather they understand the tiny little world they live in but have no idea how to get out of it or even that it's a possibility.

These kids then grow up and do what their family has always done. They have kids mid teens and just live at home soaking up the benefits.

It would take an astonishing amount of foresight for a kids from this world stop and think 'Hey, maybe if we waited a bit and saved some money it would be much better'. They'd be the first in the family for generations to think that way.

These are extreme cases, but the same mentality flows around the whole system. Everything is there to be moaned at and criticised and most importantly blamed for all your problems. This leaves you a victim of circumstance, there's nothing you could have done...

I'm quite happy to take his word for it to be honest!
