Re: don't fret!
"And if the boffins get Na-ion batteries working the price will rapidly head towards zero."
Yeah, but then they have locate and open loads of Sodium mines. We'll all be working down them!

While true, in that that is what will happen, there's not that much environmental impact from the actual mining. It's a few square Km that can easily be back-filled and restored. Unless it's a "special" area. The real problem is refining it.
The problem with most of Europe is that a minority of loud voices are against anything that might damage a blade of grass. I'm not sure exactly what some of the more extremist greenies actually want, but if they object to all forms of mining, they ain't getting any more solar panels or wind turbines.
Would it not be better to change the thermal blanket material to something less hygroscopic?
Is this a case of optical scientists only seeing the solution that is within their skill set?
Maybe both solutions together would give the filters a much longer life.
"Waymo is out-matching the average (inattentive) human"
No, as per another copmment I made, you can't compare the stats. Waymos miles are driven in specific geofenced urban areas, avoiding the city centre and only at the quietest parts of the night, ie 10pm to 5am[*]. The injuries per million miles of human drivers is measured across all road types and conditions, urban, rural and motorway, day, night, rush hours etc.
[*] I'm inferring that from the article. It may only be the actual public use taxi part of the trial that has time and geofenced limitations.
"no more than brief loss of consciousness, a sternum fracture, or the fracture of two or fewer ribs."
That seems pretty serious to me but comes across as being fairly minor in the article. I suppose, compared with death or life-changing injuries, they are, but I'd certainly not enjoy either of the latter two and probably not the first either!
"It involved a Waymo vehicle that could not slow down in time to avoid hitting a car that had pulled into its lane and then suddenly braked."
From the description, that was entirely the fault of the car in front. Maintaining a safe braking distance isn't possible if someone suddenly and without warning pulls in front of you and slams on the brakes,
Overall though, for the circumstances, this actually sounds like progress. I'd like to see the stats over time where a human had to intervene though. Is the graph showing a downward trend? Are there spikes when software updates are applied for testing? Are any updates rolled back or superseded? I doubt we'll get to see that graph since that would probably be "commercially sensitive"
My current car is approach 6 years old and 250,000 miles on it, so yeah, to some of us a million miles isn't a great deal. To others, it's more than they will drive in a lifetime :-)
But on that note, as someone else mentioned, the Waymo fleet is driving at fairly low speeds in specific geofenced areas of a city. The number specified for human drivers isn't limited by the same factors and includes all type of driving on types of roads and conditions. There are probably no stats for human driven accidents only in similar conditions so the comparis is almost certainly invalid.
Ah ok , then. Since I was as curious as you about this subject I searched Google on "people named Alexander Hanff" (without the quotes and found this page and of course I assume from your comment that both references are you rather than two different people.
You do seem to have quite a unique name and, of course, your media presence drowns out anyone else with the same name :-)
Well, there seems to be a couple of Alexander Hanffs in Poland. I didn't search any further since Google has many, many li9nks to to the author, but it's not beyond the bounds of possibility that ChatGPT isn't able to tell the difference between people, or at least not always. That could explain the incorrect place and date of birth and the incorrect report of his death. But this still doesn't explain why ChatGPT then went on to make up fake obituary links other than it went down the "create a fictional story" path based on the "facts" it had already discovered.
"It's kind of surprising that the number of photobombs has only doubled."
Not really. The relevant number isn't the the total number of new satellites. It's the number of new satellites higher up than Hubble minus those that have been de-orbitied as EOL. Most of the new sats by total number are Starlink and most of them are below Hubble.
Tomatoes are vital for powering calculators
...and some are have a small solar cell in the case good enough to run of the lights in the room, never mind actual daylight and therefore don't even need batteries.
(And no, I don't care that it doesn't work in the dark. I can't see the keyboard or display in the dark anyway!!)
"I recently typed the following digits into a calculator: 3604.59/(40*8). Anyone who can correctly explain why I wanted the result to that calculation from no other context gets a free upvote. Since it's based on an earlier calculation, it's a bit unfair. Here's another one you can try: 3*261*7."
The question is incorrect since the answer should, of course, be 8008135.
What sort of cable ran out of the spool at the back of a wire guided missile? That had to be light and able to spool out at pretty high rates and survive the exhaust flame of the rocket motor :-) I suspect a nice thin and flexible fibre optic would not weigh too much and won't need any protection if it's free spooling. Might be different if the "wire" is expected to move, be pulled or dragged etc. or the 'bot is expected to back track on itself. You probably don't want to drive over unprotected fibre when the dust or whatever it's sitting on has very sharp edges (something we already know about Lunar dust)
"Neuralink insiders who spoke about the animal investigation last year reportedly called the surgeries "hack jobs," and in-house scientists expressed frustration at having to perform surgeries so quickly and in volume."
Naaaa, probably not a good idea with anything medical but especially not brain implants.
And even a "Chief Science Advisor" with special skills in Maths and Biology is likely to be so overwhelmed by her own field, it's probably difficult to advise on anything else. Hopefully she's fully capable of knowing who to ask. Science seems to be very compartmentalised at the more rarefied levels of real experts. So much to learn and know in ever more specialised fields that there's not much time left to have any expertise in other fields. Chief Science Advisor needs to be a science aware administrator or, as per the articles, a jack of all trades science or SF writer who knows who to ask for help.
Agreed. The bit of the article that states "The bottom line is that steel was being used in Western Europe without any external influence bringing it to the region," seems to be a bit of a leap and/or a great assumption. It is absolutely likely that steel was invented multiple times in multiple locations, but nothing in the article makes the Iberians steel definitely a local invention. Trade and knowledge transfer has happened for a long as humans have "owned" stuff and that far back in time it's nigh on impossible to definitively state if something was invented locally or the knowledge was imported.
And, of course, it IS interesting and valuable research, pushing back the dates of steel production and usage in that area and helping us understand a little more of the history of humanity.
I wonder if MS enforced "updates" could result in legal challenges from people with certain medically defined disabilities. Some mental illnesses and disabilities make it extremely difficult for some people to accept or adapt to changes. At least in the past, you could install Windows and then never install an update unless you chose to. Now, every time you switch on, there's the possibility that the basic desktop could be different never mind that other stuff has changed, moved, been removed or added.
@vcragain: I'm not implying that this is you, but the way you wrote sort of implies that you don't like change, which triggered the above :-)
"following the previous official denial that it was the wet market, not the coronavirus research lab across the road."
Well, not quite "across the road". Technically, it's "across the road", but also across quite a few other roads too, then over a fairly large river and then over quite a few other roads. More like a few miles.
"also involved behavioural changes,"
On the other hand, if those behavioural changes helped people understand a little more about the situation and helped, then who can say if those same behavioural changes could have been achieved by other means? Actually wearing a mask may or may not have been helpful, but the behavioural changes that mask wearing caused does seem to have helped.
"I'm sure the scales are WAY off for that, but it's an amusing thought."
Upvoted for the idea :-)
But, or should that be butt?, scaling up or down with liquids rarely works well. Just look at the difficulties experienced by modellers in the TV and film industry when it was actual models, not CGI. Scaled down ships could look ok, but the water never quite "worked", even with all their cameras trickery and film playback speed adjustments. Same with fire and explosions. What works on a tiny scale with a miniscule nozzle, a tiny drop of pee and some frequency adjustment isn't likely to translate when trying to eject a football[*] sized "droplet" :-)
The round one, not the faux one that's more sort of ovoid and rarely kicked so not really a "foor"ball :-)
PS. Did these researchers just discover biological inkjet printer nozzles? Didn't Canons Bubblejet technology use piezo crystal to eject the ink droplet? Or was that heat and HP did the piezo thing?
"and the UK Moonshack will run on GMT"
You mean the mock-up at the Leicester National Space Centre still awaiting a launch opportunity and funding decades after Tuvalu have moved their entire population somewhere a bit drier and well above sea level, such as the Sea of Tranquillity?
Represents the UK space programme ---------------------->
Of course they'll disagree!!! The entire world will take the opportunity to create a metric time system just for the Moon, doing away with all those silly multi-base calculations that cause us Earthbound timekeepers so much grief. Except for the USA, who will insist no only on retaining "traditional" units, but adjusting and fudging them to make them fit. Or maybe switch to the Trump-o-second, a value with no fixed meaning, is almost always smaller than it seems and varies most wildly up when courting lunar investments and wildly down when the tax man come a callin'
For non-UKains, Taken Without Consent, or TWoC, is lower down the scale than theft since it's the crime of taking something, usually a car, without the intention of permanently depriving the owner, eg joyriders, or even just taking dads car without asking him and getting pulled over for no insurance or having prang and cops arrive on scene.
And additionally, unlit roads outside of built-up areas which are national speed limit by default[*] unless otherwise signed and don't always have repeater signs, especially the more rural ones.
It seems speed awareness courses don't actually cover everything that the Highway Code covers in relation to speed limits based on two testimonies above, which is the actual "go to" place to learn about the rules of the road, something every driver is supposed to learn before they even pass their test, not at a speed awareness course after they broke the rules.
* Other caveats may apply. It's all in The Highway Code for those who care to read it.
Auto-dip? Oh FFS! It's bad enough we have to suffer people driving with headlights on because it's a bit cloudy, or nearing dusk, where sidelights are all you need. I've seen car auto headlights come on because the sun is low in the evening and the road goes between embankments. Coming out the other end, the sun is still shining, I still need my singlasses on, but all those "clever" cars don't quite see enough light to turn of the fscking headlights.
Worst case was dealing with a driver who was in a hire car without auto headlights and didn't know where the light switch was so driving up a motorway in the dark without lights. Stupid driver was old enough that auto-on headlights were not around when he passed his test but still thought it ok that if he didn't know how to switch the lights on it was still ok to drive. Allowing drivers to think they can switch to full beam always and let the car worry about when to dip them is just asking for trouble when we have people like that on the roads.
