I have a 5-6m high grapefruit tree, and they... do not survive the fall. This material sounds cool but I hope it's better than my grapefruit.

Pomelo has a bit of a different ratio of rind to fruit than most grapefruit.

> produces particularly pithy progeny > fantastically fastidious on fruit quality Great alliterations. Great writing all around. This just made my night.

I'm always amazed by the Anglo-Saxon attraction for alliterations :-)

Amazing alliterations always achieve admiration.

This is not the place nor the time.

Why not? If it's the time and place to praise him, then so is the time to point out his wrongdoings.

It's just tedious virtue signalling, rather than a contribution to the thread. We all know he did things that are considered abhorrent when viewed against the current, moral zeitgeist.

What does literary ability have to do with anything else a person has done? Would Macbeth or Pride and Prejudice have been worse books if they were written by Hitler for example?

Hitler is not praised the way Churchill is in mainstream.

Hitler was a terrible author.

Are you seriously trying to compare the achievements of Hitler and Churchill in a morally neutral context?

Even though you yourself can judge a book only by its contents, when discussing it you will inevitably run into people who will bring the merits of the author into the discussion. It's called "The death of the author", and I invite you to look up the excellent videos covering the topic on YouTube.

I'd rather invite them to read the original Roland Barthe's essay (1967), which has that same title. Additionally, one can read New Criticism's authors on what they called the "intentional fallacy".

I personally wouldn't spend my time skimming through clickbait-y YouTube videos in hopes that I find one that is actually informative instead of a half-assed presentation made to maximize monetization.

It would probably not be very good at cutting, and would just get very hot. Just because the blade doesn't wear away doesn't make it good at cutting. One way to make something resist abrasives is for it to be/sustain very high temperatures. If you can survive a hotter temperature than the abrasive (quite low for diamond, higher for sapphire) then it will be much less effective.

Pretty sure once this new material gets hot enough the aluminium substrate will melt and it'll cut just as well as anything else.

You'd need direct heating, a conventional blade still would not work. The alumina spheres hold off the cutting edges and block heat flow from hotspots. A small amount of aluminum foam will melt, but once it's far enough away from the hot zone it'll just serve to conduct heat away from the ceramic much more rapidly than it otherwise would.
