Like all traffic infrastructure, there's variants that work for such situation. Roundabouts can have bypass lanes, a protected (right) turn that allievates that issue. In the UK you see these, and also designs where the through traffic

What about the Terrascope [1] concept instead? Using the Earth's atmoshpere as a refractive lens. This requires a telescope of L2 rather than some 540AU away for a solar gravity lens. Not as powerful as the latter, but much more do-abl

I agree. It would depend on the definition of "far-field" in this example, even for a quasi-Bessel beam there is a near region that maybe useful for this example given a large enough aperture. This paper [1] demonstrates the reduc

I think for the any initial project, we'll have to resort to 1km scale laser arrays. These would allow for a beam with a low dispersion so there can be a good initial acceleration. After a few hundred AU, the probes should be close to

Is a single probe subject to 100 GW? Isn't that just the output power of the laser array. If that 100GW is over 1km2, the incident light is 10W/cm2 and mW levels of heating. 1km2 is typical for these ideal to minimise the laser di

For a Gaussian laser beam, a good metric is the Rayleigh distance, which is the distance where the beam diverges to sqrt(2) of it's initial beam size (waist) [1]. It is proportional to the square of the beam waist and inversely proport

There's a bit of difference between the aims of astrophotography and professional astronomy. Ones getting a subjectively good image where the other is getting an objectively good quantitative measurement. Do the software "tricks&q

My UKRI stipend is less than national minimum wage. And is also without any employer benefits. I'm lucky to have a spouse that supports me through it. Many in the department are now struggling to attract new PhD researchers within the

The fact we have released code before the paper is wild. Typically the promise of open sourced code never comes to fruition

The energy required to alter nuclear states is often in the MeV energy range, where Thorium is a rare example that has a very close state to the ground state, seperated by 8.4eV (100,000 less energy) This means that to exicte to this nuclea

If atomic clocks become a few orders of magntidude better than the current state of the art (see atomic lattice clocks) then such clocks would do direct gravitational wave measurements and measure some fundemental constants. The latter is i

I'm happy they have some data with respect to re-entry. It would have been nice to see the vehicle survive for longer, but there's something to go forward with.

It was the arrogance that they thought that these subpostmasters had been doing this for years, and just been caught out by their new computer system. The contempt for their staff is insane

If it was a better algorithm - then of couse. You wouldn't be a very good software engineer (or scientist) if you couldn't recognise that. This has veered off from my original point. In that saying "follow the science" i

Wonderful opinions can come from anyone. Are these scientifically founded opinions. Not necessarily, hence why "following the science" is valid if you are following experts in their field. If you're a software consultant, wou

Climate models are fundamentally physical, but I don't have the insight in the field to have the deep insight to make qualified opinions. I could after significant research as suggested. But that is a significant endeavour, hence follo

It isn't if you aren't a scientist in that field. As you're not qualified to do otherwise. As a physicist in quantum sensing. I follow the science (opinion) of climate scientists as they're the experts of that field. And

It does make me wonder how a reviewer can truly review a CS paper without running the code.
