Ping!..............

Not sure “boron arsenide” is the message you want to send during a marriage proposal

[crusty old prospector]

Cool. I found some boronic arsenio in my back yard last week.

“You shouldn’t let a theory prevent you from discovering something even bigger, and this exactly happened in this work,” Ren said.

In other words, Professor Ren is saying "The science is never settled."

Good for him!

“I’m not saying the theory is wrong, but an adjustment needs to be made to be consistent with the experimental data.”

??? Doesn't that mean the theory is wrong?

[JZelle]

Shine on you crazy boron arsenide. If this doesn’t get them back together, nothing will.

[Magnum44]

Meh, I solved the heat conduction problem back in the 80's.

??? Doesn't that mean the theory is wrong?

It doesn't mean the theory is 'wrong'. It just means that the theory is not 'correct'.

[Callahan]

Interesting. If these results hold up, it could change how we handle heat in electronics. The question is whether this can be produced reliably and integrated into chips at a reasonable cost. If they figure that out, the biggest upside is energy savings for the data centers that the Ai industry relies on.

[crusty old prospector]

I love melting nazis.

[Red Badger]

The electronics industry has been using boron and arsenic for many years, so integrating it should not be a big problem.

The the ‘trick’ is to make flawless crystals at scale.................

[Celtic Conservative]

If the science is settled, then it’s not science. Knowledge is a moving target.

[catnipman]

now they just need to figure out how to make the stuff in commercial quantities:

“the large-scale and high-quality synthesis of cubic boron arsenide remains a significant challenge, though progress is being made through methods like chemical vapor transport.”

[Rockingham]

Yeah, I guess that even Shakespeare would struggle with such a task. “My beloved, thee are hotter than pure boron arsenide, with a wondrous semiconductor band gap” just doesn’t seem likely to stir a woman to say yes.

[Redcitizen]

Nazi them anymore.

[P.O.E.]

Or try this “ice breaker” at the next ladies night:

“Thermal conductivity levels above 2,100 watts per meter per Kelvin around here often?”

Ya never know.

[UnwashedPeasant]

Now you tell me! I just filled my furnace with diamonds.

[Billthedrill]

...an adjustment needs to be made to be consistent with the experimental data.

What blasphemy is this? Consistency with experimental data is racist!
