Sure, depending on the application you can just redesign to larger gauge aluminium. Aluminium has useful mechanical properties that trump the lower conductivity (such as power lines,where thermal cycles can make copper brittle). You could a

I always heard that the main reason for the leap second was that the british didn't want the prime meridian moving away from Greenwich (i.e. it is a weird political thing).

Only if they are all wearing high heels... It isn't pressure that typically causes damage though, it is shear stress or frictional power.

Basically this plot is why. Efficiency versus speed characteristics due to aerodynamics of propellors versus cowled rotors. Turboprop for short low flights, high bypass turbofan for long and high flights. https://en.m.wikipedia.o

That's interesting. Unclipping the rail is a bit of an exercise though. Makes sense that it must be in tension, otherwise it would move on unclipping. I guess they just measure it in the morning. All these types of devices are less pra

Part of the problem is that even the state of stress at installation isn't known very precisely. I basically did some pre work on a similar idea. Working through if you could track the displacement of sleepers could you figure it out.

I've only found mentions online about spraying post buckling during repairs, but pre-emptive spraying does (did) occur. You will hear about speed restrictions on hot days to avoid buckling. https://www.researchgate.net/

There is also the nuclear weapons proliferation bit. I'm honestly more concerned about that than accidents.

Buckling at high temperature is better than fracture at low temperatures. I used to do research in this area. The "holy grail" technology would be a non destructive way to infer the "neutral stress temperature" of contin

I think if you did parse the sentiment of citations you would get something quite bland, like 90% are very neutral (i.e. the effect of X on Y has been investigated in A, B, and C). The cynic in me would say that this is because a lot of th

Have to be under 40 too, so it isn't really an equivalent to the Nobel. Maths culture is weird though, long held belief that it is a young person's game.

Athletes aren't a great example. A quick look at the literature and you will quickly find heaps of studies on eating disorders in athletes. There are obvious and not so obvious motivations (i.e. a boxer making a weight division vs body

Generally the trick is regularise the inverse square law so that below a certain radius the force clips and stops things pinging off to infinity.

Hough was looking for the tracks from charged particles in cloud chambers, so the algorithm comes home after a while I guess.

If you can lower the transmembrane pressure you will get less output for less power and no fouling of the membrane. The economics of consumer choice drive design towards higher outputs and fouling.

This idea that you need to model GR to do GNSS is very over stated. You need to correct for a GR effect, but it is a small part of a residual in a least squares problem that gets regressed away. So it is important for understanding the erro

I'd like to see a comparison with a dumb as a box of hammers controller like PI or extremum seeking on the local gradient. I can't imagine that it is learning much more than a simple strategy like this, but maybe that's my la

It's really just a floating point precision issue. Even if you represented the input matrix as a rational elementary type the output eigenvalues would be a subset of the reals and calculated as being floating point. You could get arou

5.12d is pretty hard. Seems beyond intermediate to me (but maybe I'm just soft).

Fractional quantum hall effect is a massive one. All the action is in condensed matter. Somehow less newsworthy despite being closer to practical applications than high energy physics.

That was really shocking for me the first time I went to China and watched their version on state sponsored television, around 2005. The contrast between the doom version of the news back home, to china's overly positive "15 peopl

I love the book, but it is like the apogee of McCarthy idiosyncrasy. Obsessive about guns and death and has a complete absence of women. But it is beautiful for what it is.

I think most musicians recognise that the implicit rules are so complex that any reductive approach is going to fail if you want something like a simple formula for generating interesting music. It's just like language.

It's just the Knuth quote "Science is what we understand well enough to explain to a computer. Art is everything else we do." There is nothing wrong with trying to turn an art into a science. Music just has a bunch of implici

Navier stokes are incredibly important pdes for science and engineering, yet proof of even the existence of solutions is not currently available. Numerical methods are far more important than analytical solutions.
