The Large Hadron Collider is small beer. Give us billions more for bigger kit, say boffins

Spherical Cow

Re: The FCC, eh?

Ethanol and also hops. Hops are naturally antibacterial. If your beer is at least 2% ABV and also at least 20 IBU (International Bittering Units, a measure of isomerised alpha acids derived from hops) your beer is unlikely to spoil.

A long time ago in a monastery far far away (or possibly just down the road depending where you live) monks brewed ale (not beer in those days) for the local community. They did mash the grain more than once as mentioned above, they kept the very strongest ale for themselves, the normal strength was for evening consumption by adults, and the last runnings made small beer for kids and mornings.

Some modern breweries still get two runnings from one batch of grain: this is called parti-gyle brewing. Fullers is a good example of a brewery who use this method. The first runnings (strongest) goes into one kettle to be boiled, the second runnings (weakest) goes into a second kettle. They then blend different proportions of strong & weak to get different strength beers as desired. If the two kettles are boiled with different varieties of hops then the resulting stronger and less strong beers can taste very different, even though they were made with the same grain.

p.s. Brewing is my day job.

Re: One ring to rule them all?

My first thought was why not build one around the equator and be done with it. But... oceans are tricky and so are plate tectonics. OTOH there are no oceans on the moon (misleading Latin names notwithstanding) and it is geologically stable.

But only a lunatic would suggest that.

Re: Venus has a weird spin.

And Pluto has a weird plane.

Typical! You wait ages for a fast radio burst from outer space, and suddenly 13 show up

Re: Fingers crossed

Fast Microwave Bursts. Detected at Parkes (as were the first FRBs). Unexplained for ages. Turned out to be a technician heating his lunch in the staff canteen and opening the microwave door without pressing stop first.

Spherical Cow

Fingers crossed

I really really really hope FRBs don't turn out to be as embarrassingly mundane as FMBs.

Fly me to the Moon, let me play among the stars. Do you think we could get another probe to land on Mars?

The Clangers do not live on the moon. They live on a planet, across the vast emptiness of space, the silent nothingness between the stars.

What's 23 times the size of Earth, uncomfortably warm – and has astroboffins excited?

SpaceX's Crew Dragon shows up at pad 39A, nearly 8 years after the last Shuttle left

Spherical Cow

Re: What's in a name

According to the documentary series, the Soup Dragon lives on either a star or a planet, depending on which episode you watch. Definitely not the moon though.

Forget 2019's tech biz takeovers, here's the mega-merger everyone's talking about: Milky Way and LMC, coming soon

Re: There is no mass, their model is wrong

If there is no mass, how come I'm heavier now than I was before the Christmas hols?

Re: "Knock us out of the Milky Way and into interstellar space"

It would take a Marathon to get there (at least that's how it looks now from this far away).

Astroboffins spy a rare exoplanet evaporating before their eyes

A sheep is approx 100kg so that's 100,000 sheep per second.

There are approx 10 million sheep in Wales so that's 1% of Welsh sheep per second.

All the sheep in Wales would be blown away in less than two minutes.

Phew, galactic accident helps boffins explain dark matter riddle

Re: Surely it's easy?

Flat batteries, probably. I have the same trouble with my torch.

Spherical Cow

Where is Moon Child?

The idea that the amount of dark matter is increasing with time kind of reminds me of The Nothing in The Never-Ending Story.

Lasers would be more fun

But that would ruin the alliteration. Bouncing bombs? Or perhaps something to do with Arthur Jarrett (a convicted criminal who has been allowed to choose the manner of his own execution).

There's no mystery

There's no mystery about the origin of water on Earth. The water has flowed across the surface of the planet from Britain where it rains all the bloody time.

China on its way to becoming the first nation to land on the far side of the Moon

Re: eliptical orbit satellite...

That reminds me of a record player I used to have. While it played the first record, I could stack up to five more on the spindle, which had a little lever thing to keep them suspended above the first. When the first record ended and the arm returned home, the lever thing would let the next one drop and that one would then be played. Imagine that! A total of six LPs playing back to back (only one side of each, mind you) without the need for any human intervention! Happy days.

Paddington Bear came from Darkest Peru, which probably receives just as much sunlight as the more well-known parts of Peru. Also, the Dark Ages did not have shorter daylight hours than ages with more complete written histories.

I would imagine that one situation where subs would be better than ships would be mapping the seabed under ice.

It might make sense to use a cheaper non-stealth unarmed mapping sub for that. Possibly even a drone sub?

Re: making appear commonplace

Landing first stages in the mid- Atlantic is unlikely to be a "disaster" even if it goes completely tits-up: the Atlantic is a very empty place.

The chances of hitting a ship are nowhere near a million to one (because odds like those happen nine times out of ten, and it hasn't happened yet).

Sorry, but NASA says Mars signal wasn't Opportunity knocking

Spherical Cow

Something odd is going on here.

The MRO relayed a message from OPPY but the message wasn't from OPPY. How does a mistake like this even happen? Isn't relaying messages correctly one of MRO's core functions?

Re: send the Orion-ESM combo beyond the Moon to check it out

Sorry* to be pedantic, but the intro to the first documentary about the Clangers clearly states that they live on a star very far away, not on our moon.

Boffins have fabricated microscopic sci-fi tractor beams for real

A tractor beam is what is emitted by Farmer Brown's one working headlight. The beam can't pull, and neither can Farmer Brown, but his tractor certainly can.

Fat chance: Cholesterol leads boffins to discover world's oldest animal fossil – 558m years old

Spherical Cow

Just one thing I don't understand...

"These fossils were located in the middle of cliffs of the White Sea that are 60 to 100 metres high. I had to hang over the edge of a cliff on ropes and dig out huge blocks of sandstone, throw them down, wash the sandstone and repeat this process until I found the fossils I was after."

I understand the helicopter, the ropes, the washing, etc. What I don't get is this: how the hell did he know where to look?

A well engineered mercury bearing only needs a surprisingly small amount of mercury. Even if it is quite large, you only need a tiny gap between the outer bowl and the thing floating in the bowl. When visiting lighthouses I've been surprised at how little mercury they use to float their lenses.

Re: drone ship

His ideas are getting progressively weirder.

1. Make cool electric cars: that's a great idea.

2. Make reusable space rockets: risky, but luckily it's going well.

3. High speed trains inside vacuum tubes! That's just loopy.

4. Dig loads of tunnels and put all the cars underground: he's reached a new low with this one.
