The school was one of the better state schools in West London - the kids were 17 at the time. At the end of the school year they give them a couple of weeks to do a project of their own making. This particular project was the kids initiati

It's not that you cannot transmit from a high altitude balloon over the UK, but you are very restricted in transmit power and frequencies. My son and a friend of his built a Muon detector and sent it up under a high altitude balloon a

The problem with this talk is that it's almost content free. He has demonstrated that sometimes we (and other animals) misperceive things, or construct in our heads what we expect to see. He has demonstrated via simple virtual world

According to FR24 [0], the decrease in altitude corresponds to an increase in groundspeed. If you're flying through descending air, the groundspeed generally wouldn't change, just the rate of climb decreases. Even if you increas

Minix is BSD licensed and is present in Intel CPUs[0]. So I think it would be a toss-up as to whether BSD or GPL-licenses OSes are more widely used overall. To be clear, I'm making no comment on whether Intel using Minix is a good th

For the most part, Heathrow doesn't do mixed-mode operation (where you have takeoffs and landings on the same runway). However, my understanding is that this is not for safety reasons, but mostly to give people living under the flight

The problem is that if your monitor is set up so that a white background looks OK, then all photos, video, etc, will look too dark. If your monitor is set up bright enough for photos to look good, then text on a white background is too dazz

Yes, our thermostatic valve has around 270 degrees of travel on the temperature dial (which is separate from the water flow dial). Of those 270 degrees, it takes about 140 degrees to go from my preferred temperature to my wife's prefer

[SIP author here, for better or worse] SIP's victory over H.323 was definitely an odd story. Henning Schulzrinne wrote a draft called SCIP, which was essentially HTTP for multimedia calling. SCIP overlapped with what Eve Schooler an

SIP didn't start out complicated. If you go back to the origial internet drafts Henning and I wrote, it was really really simple. Well, our original UDP-based SIP was simpler than Henning's TCP-based SCIP, but neither was complic

Of course at some point in the future if a lot of people with EVs say yes to this deal, the price range will narrow significantly, and eventually stabilize to the point where it's only just profitable given battery degradation costs.

I wonder if anyone has researched whether it's actually good to remember everyday things. I can watch a movie or read a novel, enjoy the experience, and the next day not really remember much about it. Often I'll get half-way thr

Way back when I was a student living in an old rented house in London, I went into the bathroom to find the bulb had blown. It was a pull cord switch, so I didn't know if it was on or off, but knew I wouldn't be so stupid as to s

Perhaps the reason they need to recharge in descent is less to save energy for the next flight, but more the need to have reasonably well charged batteries in case they need to perform a go-around. Rate of climb when the batteries are disc

I've been a happy customer of A&A for 18 years now - you do pay a little more, but well worth it for the unfiltered service and excellent tech support on the very rare occasion I've had a problem.

I think many people do that - it's very hard to write up a compelling proposal without having spent some time working on the idea to see if it's viable, but there's often no funded way to do preliminary work on an idea. If y

I've had a pretty successful research career, but it's very rare I've had a project that actually delivered what I said it would on the funding proposal. Something more exciting has always come along while we were working on

I know you're joking, but I'll take you seriously anyway. Using a magnet could actually make things worse. There will be some mass that the magnet can lift fast enough to clear a path, but over that mass it will only partly lift

The hypothesis that the nail either punctures on the first rotation, or not at all, misses that something is different on subsequent rotations, namely that the nail experiences centripetal acceleration once it is embedded in the tyre. Yo

As a boat moves through the water it creates a bow wave. The wavelength (ie crest to crest) of the bow wave increases with boat speed. Once the wavelength of the bow wave equals the hull length, the boat will start climbing the front of t
