No, the title is poorly worded. They are testing a technology that could redirect an asteroid, there isn't one that is currently a concern.

Would any of that really make it heat more efficiently though? You'd need at least two magnetrons, some sort of computer vision system, and a computer to do the necessary calculations. Even if you could practically produce an interference pattern that's better than a single standing wave, I suspect you'd lose more energy than you save.

I'm happy to accept that I was wrong, in fact this is a very interesting bit of technology! I didn't intend to be rude, unlike you, clearly.

I'd also like to add that beamforming, despite the name, does not actually involve creating a directed beam. As I described the antenna still sends a signal out in all directions - multiple antennae work together to create an interference pattern with a stronger signal where a device is located. While I wasn't aware of this technology, it is not as "directed" as the name implies and wouldn't necessarily have applications inside a microwave oven, especially since the wavelengths used are pretty long, so I don't think they would not have much flexibility to create the kind of precise pattern that cooking something while skipping the empty space would require.

Routers? Do you mean Wi-Fi routers? Because they certainly don't pinpoint waves for each device, they send all traffic out in all directions.

Well then the average is just 1 isn't it. It doesn't make any sense to integer-ise your inputs but leave your output rounded.

Bioinformatics is the last door at the end of the hall. Be warned, we put it down there for a reason.

Look I spoke to Bill Nye and he said all scientists can grow cells sometimes, as a treat.

No, you probably don't remember the crappy ones from when you were a kid, but they were there. Survivorship bias.

A pizza is larger than two of another just before it hits 1.5 times the radius (sqrt 2 times, to be exact, about 1.41). So if the radius is 1.5 times bigger, like in the OP, you always know it's more than twice the area.

Scots isn't just an accent, it's a language in its own right.

Although honestly I'm not sure how much of this is Scots and how much is just specific to Scottish twitter lol

So actually having done some more reading this isn't Scots - I'm fairly sure this is Scottish English which is somewhat a merging of Scots with English.
