Mitch McConnell: “These shots need to get in everybody’s arm as rapidly as possible” or they’re locking America down again.
Never has there been a pandemic where they have to threaten or bribe the population to receive treatment, it speaks volumes in itself.
I have two of them. Both are now illegal in California. I don’t know if my CCW in CA is good enough to justify ownership or not. Things there are strange.
They are underwater firearms (single shot) for use against sharks or fish that are too large for a spear that you might wish to catch (think large groupers).
Nobody wants to get THAT close to a shark, and you mount them on the end of a pole (Hawaiian sling) so that they fire on contact. The button that you see simply cocks the weapon. The bang stick above fires a .50 BMG, but the .44 Magnum is a far more practical cartridge for this application. The .44 Mag doesn’t hurt the ears of the shooter/diver the way that the discharge of a .50 does.
When you use them, the target fish will expell a lot of blood and tissue: gore – bringing sharks. It’s a one-target, surface-and-gone sort of event.
Magnetars that are also Pulsars – Cool
J1818.0-1607 is one of a group of only five known magnetars that act like pulsars — which are fast-spinning neutron stars that emit powerful beams of radiation from their poles.
It’s an interesting time for people who study neutron stars (my favorite class of celestial objects). If I was younger, I could do that for a living. Now that I’m old, I’m just a magnetar groupie.
Neutron stars are remnants of supernovae, incredibly dense objects — second only to black holes — that compress more than a Sun’s worth of mass into a sphere only about as wide as a city. Magnetars, are a subset of neutron stars that sport the universe’s most powerful magnetic fields. The fields around these stars are roughly a million billion times stronger than the magnetic fields of Earth.
Because of the nucleon binding energy, only elements up to iron can be produced in the conventional way inside of stars. Anything heavier than iron needs to be produced in another way because it is an endothermic reaction and requires huge amounts of energy. Some heavy elements are produced in supernovas but there is a subtle problem with that. While there certainly is enough energy in a supernova explosion to produce the heavier elements, most of the mass that is blown off in a supernova is hydrogen. It would take an immense amount of energy and a string of complex, and highly improbable reactions to convert that much hydrogen into elements as heavy as gold and lead.
In nuclear physics there are two processes that can produce heavier elements, named the r-process and the s-process (unimaginatively the r and s stand for rapid and slow respectively). The s-process takes less energy and much lower neutron flux and can happen over long time scales. In the s-process, heavy elements are built up slowly one neutron at a time and allows for neutrons to decay into protons.
The r-process requires huge amounts of energy and truly astronomical neutron flux. A parent element is bombarded with a huge number of neutrons to make an extremely unstable isotope. The only thing keeping it from decaying into smaller elements is the rate at which neutrons are bombarding the nucleus. While a supernova has enough energy for the r-process, there is a distinct lack of neutrons to achieve the neutron flux necessary for the r-process to take place. It does happen, just not at a high enough rate to explain the amount of gold, lead, uranium, and other really heavy elements we observe in the universe. So while normal stellar processes can explain the carbon, oxygen, and nitrogen we see, and novas and supernovas can explain the amount of aluminum, iron, nickel, and zinc we see, neither of those can explain the amount of gold, silver, lead, and uranium we see.
This is where merging neutron stars come in. In the collision, there certainly is enough energy for the nucleosynthesis to take place, and because there are two massive sources of neutrons being ripped apart, the problem of meeting the minimum neutron flux is solved.
I used to go to the Movies on Weekends
Now there is nothing but woke films, films about people transitioning, slasher movies, cartoons and ethnic flicks. I guess nobody wants my money anymore.
Have you ever noticed that on every Youtube Sasquatch documentary they begin by saying that “Cleetus has been awake for three days and nights, drinking paint thinner, but he knows what he saw.”
