Some people like to talk about immigration into the the US, but they don't seem to want to talk about the millions of people who are leaving the US...

"According to a Gallup poll from January 2019, 16% of Americans, including 40% of women under the age of 30, would like to leave the United States."

Retro SciFi Film of the Week…

Jurassic Park (1993)

In 2013, this film was re-released so I think even most young people have seen it. Plus it was turned into a franchise so there are about a half-dozen of these Jurassic blah..blah..blah films out there now. For those of you who have been extinct and recently revived, this film is about a guy who took DNA from fossils and de-extincted various dinosaurs and put them into an amusement park. What could go wrong?

I’m including this one in the Retro SciFi series because it will likely be in the news soon. It stars Laura Dern, Jeffrey Goldblum, and Sam Neill.

One of the notable aspects of this film is that it marks the transition from the use of mostly practical effects in the film industry to primarily using digital effects. The dinosaurs were mostly high-quality robotic puppets, but digital techniques by Industrial Light and Magic were also used for scenery and composites.

There’s a real story here and top-notch acting so it’s not just a bunch of FX, which it makes it worth watching.

Accessible video description:

Goldblum’s character is asleep in a jeep when he hears the thunderous footsteps of a dinosaur. He looks at a puddle and the water shows waves of disturbance from the seismic vibrations. (Glodblum: Anybody hear that? It’s a um... an impact tremor is what it is… Fairly alarmed here.) He calls and gestures to two other characters who jump into the jeep (“Start the engine!”) and they speed away as a T-Rex chases them. (“Must go faster.”) The T-Rex gains on them. Goldblum accidentally bumps the stick-shift in the jeep. (Driver: “Get off the stick, bloody move!”) (Dern: “Look out!”) The jeep drives under a fallen tree trunk and the T-Rex crashes through the tree trunk shattering it into pieces. (more screams) The T-Rex tries to bite them and he bumps his head against the jeep. The jeep finally pulls away and escapes. (Goldblum: “Think they’ll have that on the tour?”)

>"please stfu, these type of masks are ineffective at preventing the spread of viruses, even n95+ worn properly only offer marginal protection- and in most cases increase respiratory infections
"pointless virtue signal. good try though"

A properly worn N95 is greater than 95% efficient at filtering virus particles. The most effective respirator at a reasonable price is an elastomeric N100 / P100, which filters 99.97% of virus particles.

More people died in the US during the past half-hour from COVID-19 than died in the Nashville shooting.

Please wear your respirator when you are in a public place or anywhere where others are breathing in the same space.

spoiler – TruthBeTold explanation… 

This one is 100% true.

Depleted uranium is what is left over after most of the U-235 is removed from naturally occurring uranium. It is mostly U-238, which is non-fissionable (it can’t support a chain reaction). There are other metals that are more dense than depleted uranium, but they are more expensive, so they use depleted uranium and add a small amount of other metals to make it a hardened alloy.

Uranium-238 has a very long half-life of billions of years, so it decays very slowly and produces very little radiation. All of the radiation from U-238 is alpha radiation, which does not penetrate very well – it can be stopped by a sheet a paper and only travels a few inches in air. Some of the daughter isotopes in the uranium decay series produce beta and gamma radiation but the majority of radiation in the complete decay of uranium to a stable isotope is in the form of alpha radiation. Only the surface of the rounds will actually emit alpha radiation into the air, and that radiation will only travel a few inches.

So nearly all of the radiation from depleted uranium will be converted to heat before it reaches any of the soldiers inside a vehicle that is carrying depleted uranium ammo. This heat will contribute a small portion of the heat within the vehicle but, for example, in a tank most of the heat will come from the putt-putt engine used to power the vehicle. In fact the body heat from the soldiers produces more heat energy than the radiation from the decay of the uranium in the ammo rounds.

There is a potential danger though from the depleted uranium rounds (beyond their use as a deadly weapon). If microscopic pieces of the depleted uranium are dislodged from the material and become airborne, like when the shells are bumped together or scraped, then those airborne particles can be breathed in and become lodged in the lungs or ingested into the digestive system. In that case then the alpha particles can strike tissue and damage DNA which could cause cancer. If a sliver of the metal penetrates the skin, that can also potentially cause damage to the DNA of the tissue it is in contact with.

Also, one of the daughter elements in the decay of uranium is radon, which is a gas. So when the radon is produced it can be released into the air inside the vehicle. Since radon has a half-life of about four days, it can decay into polonium particles in the air (which have a half-life of about a month) and the radon and polonium can accumulate in the vehicle and get into the lungs where it can damage tissue. If the vehicle is well ventilated then there is little risk of that happening.

OK, there’s more but this way too long already...

Depleted uranium is used by military units all over the globe as projectiles for various guns used in aircraft and armored vehicles. The advantage of using uranium is that it has a higher density than lead or other metals so that the projectile can deliver more force on impact. Also, the nuclear radiation from the decay of the stored uranium ammo rounds in the vehicles helps to keep the soldiers warm.

FYI, the "5-second rule" says that if you drop food on the floor and pick it up within five seconds, you can still eat it.

It's a running joke and there is no scientific evidence for it. If there are harmful contaminants where the food falls they will transfer to the food as soon as it touches them (due to the electrostatic effect).

If the food is moist, contaminants will transfer more easily because water is a polar molecule and readily adheres to other molecules.

(and you thought this video had nothing to do with STEM?)

A quote from amnesty.org... "Protest is an invaluable way to speak truth to power. Throughout history, protests have been the driving force behind some of the most powerful social movements, exposing injustice and abuse, demanding accountability and inspiring people to keep hoping for a better future."
