Big Bomb

NYT: "New Video Shows Largest Hydrogen Bomb Ever Exploded"
Last week, the Russian nuclear energy agency, Rosatom, released a 30-minute, formerly secret documentary video about the world’s largest hydrogen bomb detonation. The explosive force of the device — nicknamed Tsar Bomba, or the Tsar’s bomb, and set off on Oct. 30, 1961 — was 50 megatons, or the equivalent of 50 million tons of conventional explosive. That made it 3,333 times as destructive as the weapon used on Hiroshima, Japan, and also far more powerful than the 15 megaton weapon set off by the United States in 1954 in its largest hydrogen bomb blast.

Crash The Universe?

"Could We Force the Universe to Crash?"
If we’re all living in a simulation, as some have suggested, it would be a good, albeit risky, way to find out for sure...

But the neatest test of the hypothesis would be to crash the system that runs our simulation. Naturally, that sounds a bit ill-advised, but if we’re all virtual entities anyway does it really matter? Presumably a quick reboot and restore might bring us back online as if nothing had happened, but possibly we’d be able to tell, or at very least have a few microseconds of triumph just before it all shuts down.

 The question is: how do you bring down a simulation of reality from inside it? The most obvious strategy would be to try to cause the equivalent of a stack overflow—asking for more space in the active memory of a program than is available—by creating an infinitely, or at least excessively, recursive process.

And the way to do that would be to build our own simulated realities, designed so that within those virtual worlds are entities creating their version of a simulated reality, which is in turn doing the same, and so on all the way down the rabbit hole. If all of this worked, the universe as we know it might crash, revealing itself as a mirage just as we winked out of existence.
I confess to being uneasy at the idea of crashing the universe. That's where I keep all my stuff!

That's fast enough to make visible the relativistic phenomena of time dilation and length contraction, turning the star into an interesting sandbox for curious physicists.

A True Story (Ἀληθῆ διηγήματα, Verae Historiae) is a novel written in the second century AD by Lucian of Samosata, a Greek-speaking author of Assyrian descent. The novel is a satire of outlandish tales which had been reported in ancient sources, particularly those which presented fantastic or mythical events as if they were true. It is Lucian's best-known work.

It is the earliest known work of fiction to include travel to outer space, alien lifeforms, and interplanetary warfare. As such, A True Story has been described as "the first known text that could be called science fiction".

Movie Recommendation: A Town Has Turned To Dust

I recently watched "A Town Turned To Dust", available on YouTube.

Excellent 90-minute play, written by Rod Serling before Twilight Zone. Although it was written in 1958, it touches on various themes of human nature and political behavior that are chillingly relevant for today.

Bonus #1: It stars a very young William Shatner, who does a great job of playing the lead role as an unsavory storekeeper in an Old West town.

Bonus #2: Includes embedded 1950's commercials. OMG.

Serling's experiences in getting the script approved apparently pushed him to the direction of science fiction:
Network pressure and sponsor meddling was making it almost impossible for him to say anything meaningful in a straight dramatic setting. A series with a sci-fi/fantasy twist, on the other hand, would open up new story possibilities — and allow Serling's social jabs to fly under the radar of nervous sponsors.
"On The Twilight Zone, I knew I could get away with Martians saying things that Republicans and Democrats couldn't," he said. And a TV legend was born.

Black Hole Collision

"A supermassive black hole lit up a collision of two smaller black holes":
Astronomers from Caltech have reported that they’ve observed a collision between two black holes. Normally such an event is invisible, but this time a more massive black hole sitting nearby helped illuminate the other two as they collided. If confirmed, the findings, published in Physical Review Letters, would be the first optical observations ever made of a black hole merger.

Mega Coffee

"What Does Death Wish Coffee Taste Like? (And Is It Safe?)"
Death Wish is billed as the “world’s strongest coffee.” And although the company doesn’t release caffeine-content figures, we have seen third-party test results in an eye-opening range of 650 to 728 milligrams of caffeine in a 12-ounce (Starbucks “tall”-size) cup. By contrast, Starbucks’s dark, medium, and blonde roasts have 193, 235, and 270 mg, respectively. (Darker beans generally have less caffeine than lighter ones.) So drinking a cup of Death Wish is like drinking 2½ to 3 cups of Starbucks coffee.

After brewing a 12-ounce cup of Death Wish (using the company’s recommended brewing ratio and grind size, and our top-pick pour-over dripper), I found the taste hearty and, yes, potently strong—all coffee, no subtlety. It was stronger than two Starbucks dark roasts I compared it with, but not bitter or unpleasant. It’s what I’d expect to find in the thermos of a lumberjack or a Bering Sea crab-boat skipper.

Stricter Rules For Hawaii Visitors

More details of the mandatory 14-day quarantine for visitors to Hawaii:
The person will also initial and sign the mandatory order for self-quarantine form confirming they are aware they must self-quarantine for 14 days. By signing the legal document, they acknowledge they understand violating the order is a criminal offense and they are subject to a $5,000 fine and/or a year imprisonment.
An airport representative will collect the two forms and begin verifying their information. First, they will call their mobile phone number to confirm it rings right in front of them. If it does not ring, the person may have listed inaccurate information and is asked to verify the number. If the person refuses to provide a phone number that can be answered on the spot, law enforcement is contacted and they are subject to citation and arrest.

After the phone number is verified, an airport representative will then check the address listed for lodging. For returning Hawaii residents, the address should match their government issued ID. For visitors, the airport representative will call their hotel to confirm they have a reservation. Processing personnel have phone numbers for every hotel in the state.

Light Data

"Does a USB drive get heavier as you store more files on it?"

Short answer, "no". It actually gets very very very slightly lighter:
When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge. To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams. This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight. However, you would need to weigh more USB drives than exist on the planet together at once before the difference in weight became easily measurable.

[Off Topic] Hsieh Forbes Column: Tips For Staying Out Of The ER

[Off topic] My latest Forbes piece is now out: "Tips For Staying Out Of The ER During The Coronavirus COVID-19 Pandemic".

Here's the opening:
As case numbers increase during the current Coronavirus COVID-19 pandemic, hospital emergency rooms are becoming more crowded. Patients showing up at the ER for possible COVID will add to usual load of patients already there for heart attacks, stroke, acute appendicitis, accidents, “normal” influenza, etc.

So anything you can do to keep yourself out of the ER helps everyone (yourself included).

In that spirit, I’d like to remind folks follow some simple old-fashioned prudent practices...

Super Low Gear

"Here's What a Googol-to-One Gear Ratio Looks Like":
To celebrate being alive for a billion seconds, Daniel Bruin built a machine with 100 gears with a 10-to-1 gear ratio…meaning that the overall gear ratio is a googol-to-one. (A googol is 1 with 100 zeros.)

This machine has a gear reduction of 1 to 10 ^ 100. In order to get the last gear to turn once you’ll need to spin the first one a google [sic] amount around. Or better said you’ll need more energy than the entire known universe has to do that. That boggles my mind.

Recently developed apps using public government data allow users to see how close they are to where a confirmed Covid-19 patient has been. They can also see the date a patient was confirmed with the disease, demographic data about the patient, and, crucially, some of their location history.

At least one app, called Corona 100m, will also alert a user if they come within 100 m (328 ft) of a location visited by someone who’s had Covid-19.

Pandemic Prep Items

Australian virologist Ian Mackay offers recommendations of items to purchase and preparations to make in anticipation of potential Coronavirus pandemic:
The list included extra prescription drugs and over-the-counter fever and pain medicines; feminine hygiene products; toilet paper and tissues; and vitamins "in case food shortages limit the variety in your diet." He also advised buying items including soap, alcohol hand rub and household cleaning products.

In terms of food, he suggested purchasing cereals, grains, beans, lentils and pasta; tinned food such as fish, vegetables and fruit; oil, spices and other flavorings; dried fruit and nuts; powdered milk; items for pets; as well as soft drinks, candy and chocolate for treats.

Mackay also provided a list to be used in the event that a "severe" pandemic cuts access to fresh foods. The products "should be the last things to buy if you have a hint of when supplies might slow or stop for a (hopefully short) time."

Those include bread and wraps, meat for freezing, milk, eggs, yogurt, and fruit and vegetables. Car fuel should also be bought at this time, he said.

"But don't panic buy and don't hoard!" said Mackay.

"No One Can Explain Why Planes Stay in the Air":
[T]here is actually no agreement on what generates the aerodynamic force known as lift. “There is no simple one-liner answer to this,” [aerodynamics expert John D. Anderson] told the Times. People give different answers to the question, some with “religious fervor.” More than 15 years after that pronouncement, there are still different accounts of what generates lift, each with its own substantial rank of zealous defenders. At this point in the history of flight, this situation is slightly puzzling.
