Altera MAX 10 evaluation board is probably one of the cheapest options. You use quartus prime lite to configure it which is free, and better than the equivalent Lattice tools.

What does race have anything to do with this? Unless you believe diversity somehow leads to insane laws....

I think it has its uses. For example its really handy when changing nappies as my toddler wriggles like crazy and it helps to distract him whilst I getting rid of the poo.

I'm not sure actually. There was a lot more attention to the second crash after it became apparent that Boeing had sold an unsafe aircraft.

I mean, they specifically targeted him first. It's not that he just didn't like Kim and thought he'd take him down a peg.

Maybe because trees contain a lot of water/nutrients? Tbh I've always wondered what you've said too, though I'd just dump the wood in old mines etc.

I'm puzzled at how breast cancer could be a political issue. How so?

Ah, you're totally right. I misread the OP. Sorry.

The way it works is that the entire assembly is in a vacuum. It kinda has to be as any gas which touches it will instantly condense to it or freeze to it. You then have a dual cryostat of liquid helium and liquid nitrogen cooling down the assembly (within the vacuum). The helium and nitrogen cryostat also have a vacuum shield. The nitrogen (liquid at 77K) is a sacraficial coolant which is far cheaper than liquid helium (liquid at 4K) that you need to get to these temperatures. Your're right that thermal radiation is an issue so you have to be careful with the placement of any windows or mirrors around the device.

Souce. I have a PhD in physics where I used equipment cooled to 4K.

Not really. You just have the whole package instead a vacuum casing.

Thanks for the resource. I'm pretty sure I used it for some of my simulations of C60 molecules hexagonal packing, during my physics PhD a few years back.

I'm not sure if he's edited his post, but it is extremely rare for students to share rooms at any point of their university life. The closest thing we have is a shared study where two people have their own small sleeping room, but share a space with two desks/chairs. And even that is very uncommon.

I understand that completely. Feeling good about yourself for sticking it to the man doesn't support a family.
