> Asphalt is a mixture of aggregates and bitumen that needs up to two days before it completely cures. Whereas, Tarmac is a combination of crushed stone and tar that cures quickly.

We don't have to. For example, a ruthless train door could be made less ruthless, by having sensors that respond to someone who is nanoseconds late, to open the door, just that once, just like it's elevator door brethren, but only once.
The problem is that "inherently opportunistic people" will take advantage of the machine kindness and take an entire train full of people hostage.
The oppressive train door is a dictator everyone loves, maybe if they were also razor sharp, people would give them the respect they deserve. phwump. guillotrains. on time, every time.

For people who didn't have a great experience with their own university studies and for current students who may have had a less than stellar introduction over a covid semester, this is a great opportunity to really learn it. If you have single variable differential and integral calculus under your belt, my suggestion is to sign up for this class and give it 100%. The course is free to audit, but if you can afford it then give them your money! They'll be incentivized to make more of these excellent courses and besides, they deserve it.
This is an important time for online learning. The hype over MOOCs has died down and the dedicated remaining educators are still at it, learning from our participation. It's not perfect yet, but even today some of the courses are way better than their brick and mortar counterparts. I think this will be true for 18.02x.

The cool part is that at twilight, when the light turned on, the little bit of reflected light bounced back to the photovoltaics, adding just enough light to turn the light off, which brought the system full circle. Amazingly, this behavior only occured for about 1 minute each day.

> For many years, it has been known that China uses execution vans, kind of like specially outfitted ambulances, to more efficiently carry out its exceedingly large number of executions. The method of killing in these vans is lethal injection, which has been slowly but surely replacing the firing squad as China’s preferred means of execution, and both lethal injection and the vans are believed to facilitate the widespread practice of harvesting organs of the executed prisoners, an unbelievably appalling practice.
When isn't it? Parent was suggesting the US is underfunding the USPTO. The undisputed claim is that they got all the money they requested. If they need more money, then they should request more. My line of reasoning can be falsified by showing the USPTO didn't get all the money they requested, or that through some bureaucratic machinations submitted an insufficient budget under duress.

They seem to get 14-29 hours. Your implied claim is: that isn't enough time, for which you'll have to make a case because it isn't established. How much time is enough? What degree of "patent integrity" is acceptable, are there diminishing returns in spending twice as much time assessing a patent? What other federal programs should be sacrificed to make the patent system X% more accurate?
