  • We won’t have a clear winner. No matter which candidate “wins”, there will be widespread allegations of voter fraud. There will be protests. Biden will declare a national emergency. What happens after that? I don’t know. But I am prepared for major social unrest.

    A large number of people from both major parties are absolutely unwilling to accept a win by the opposing candidate. I’ve never seen the country so divided.




  • There are plenty of companies that will sell your name, email addresses, phone numbers, street addresses, marital status, and relative’s names. They obtain the information from publicly sold databases. I had access to one that had all that, plus the registration info for the car I drive, my estimated income, my military record, my driving record, my political party preference, and pictures of my home that had been on the realtor’s website.

    The scary one was when a phone center employee in the Philippines stole my wife’s debit card number and then did two big Western Union MoneyGram transfers to a couple of Filipino men. That means bad actors have access to the credit companies’ databases from which Western Union draws their proof of identity questions, like who holds your mortgage, where you lived when you were 10, and the make/model of your first vehicle.

    If you’re well-off enough to be a financial fraud target, paying a company for identity theft protection is probably well worth it. Put fraud alerts in with all the major credit bureaus too. That usually stops identity thieves from accessing your credit. If you use 2FA with your phone, make sure your telecom provider will not transfer your number to a new device without in-person authorization and authentication.









  • If you place a tea bag in a cup of water at 20C in a thermally isolated vacuum chamber, when the chamber pressure is reduced to or below the vapor pressure of water at 20C (about 17 torr, or 1/3 psi), it will begin to boil. The vapor produced will be at 20C and the water in the cup will be 20C and begin to decrease, because of latent heat of vaporization needed for the liquid/gas phase change. The water will continue to boil as long as the pressure is maintained at or below the vapor pressure of water at that temperature. Eventually, the water reaches 0C. Then it will stop boiling and begin to freeze as the latent heat of fusion provides the necessary heat to continue evaporation. When all the water has converted to ice, the vapor pressure is greatly reduced. The ice will sublime (go from solid to gas) still, but as that continues to cool the ice, the vapor pressure also drops. As the temperature drops, sublimation will slow until it is nearly zero. So you would end up with a tea bag encased in ice.

    In your example, if you suddenly exposed to the cup and tea bag to the vacuum of space by rapidly venting the air, the water would explosively evaporate, shredding the tea bag. You’d be left with bits of tea leaves, an empty cup, and a lot of very fine ice crystals.





  • It wasn’t any particular scientific discovery that weakened religion. It was the popularity of science fiction that did it. As Arthur C. Clarke put it, “Any sufficiently advanced technology is indistinguishable from magic.” People can now imagine how miracles are done without invoking anything supernatural. We might not have the tech to do it yet, but we have a pretty good idea of potential methods. That has placed a lot of “creator god” religions under pressure. Create life? Tech will eventually do it. Create a world? Sure, tech again. Given enough tech, a solar system can be spawned. Water into wine? We’re halfway there with Kool-Aid. We already have vimanas (those ancient Hindu flying vehicles). We call them airplanes or helicopters. We can destroy a whole city with a single weapon. So why should we worship a supreme being who supposedly did those things?

    Assuming we can conquer poverty, religions that survive will be centered around improving the human condition. Worshipping dieties will eventually fall by the wayside. It will still be a long process. You can’t dispel faith with reason and facts. And people in poverty tend to embrace religion because it gives them comfort and hope that things will be better in the afterlife.
