  1. Greetings. Human and animal eggs and sperm are routinely frozen for preservation; and read something about fertilized embryos getting the same treatment. What about plants ? Is there a way ? Can a germinated young plant, or perhaps a grown one, be preserved until a future planting/growing season ? Can annual plants be preserved/suspended from winter death until much later to continue their growth, other than greenhouses * ? I know seed banks keep thousands of varieties frozen for any future needs, but are those non-germinated seeds embryos ? This thread triggered from the uncertainty from a seed to germinate. I see there is no way to assure success to germinate a seed even by the most expert 'green thumbs' * Would an annual plant dying by winter season continue to thrive if transplanted to a tropical weather, or there would be a collision with its genetics from unexpected weather ?
  2. Would it be possible ? If there was an intention to make winter solstice for the northern hemisphere to coincide with December 31, would counting a few years of februarys with 29 or 30 days instead and substracting a day or two to other months for the same few years; then returning to 'normal' when done... Or that would result in the opposite shift direction ? I have a mental fart on it. Is there other hurdles I do not notice ?

    Dry gin...

    Hi. Rarely find a bottle not saying 'Dry' or 'London' style. Is there a not-dry gin ? Can you make it 'wet'🙄 adding something to it ? Sugar ?
  4. Interesting contraption, thanks. If uses air cored coils, generation should increase with an iron core, right ? This thread triggered from inspecting my defunct portable generator that shows no residual magnetism anywhere at all and has no brushes. Wondering if earth magnetism is used as initial development of field excitation... FC= field coil rotor MC =stator main coil SC=stator coil for capacitor PL=pilot lamp
  5. Thank you. That Worx shredder is tempting me for a while now... Do leaves come out like flour or not that fine ?
  6. Hello. A coil with a laminated iron core, put to spin... Would it generate some electric current in its windings just because the faint earth magnetism is in the way ? -No permanent magnets involved-
  7. Nellis? known as area 51; who is the top gun, master chief, six star supergeneral, total ruler, 'god' that does and plans and controls everything with total authority reporting to no one? Is from the Air Force or other branch ? Or is there someone at the Pentagon that controls that 'supergeneral' ? Seems that by ~2011, abruptly or simultaneously, many 4 star generals ceased :
  8. U.S. presidential election dictated by the electoral votes. OK. Why, how come, the democracy of an individual state differs its democracy from the United States democracy ? Each state elects their governor (State president with another name?) by popular vote instead of an electoral -county?- votes if the United States is united' ? 😦
  9. Greetings... You have a chunk of plutonium on your desk 🤥. What is the danger ? Is it its thermal emission; its electromagnetic radiowaves emission; other invisible emission; its dust particles emission; poisoning ionizing emission of (α),(β),(γ) rays ? What gets ionized nearby in its presence ? -The word radioactive confused with radiowaves to the public- If that chunk of plutonium on your desk is small as a grain of salt or larger as a golf ball, will it harm you slower or faster ? If that chunk of Pu is embedded in a plexiglas block; does it change anything ? 🤨
  10. Stoves use cast iron around the hot area. Perhaps you can find in plate form; or grille.
  11. Hello. Did not see suggested or mandatory sharpening angle range to drill concrete/masonry/tiles. What would it be with widia tips ? ============================================================== (Pasted) --- > Drill sharpening angles refer to the angles formed between the cutting edges of a drill bit and the axis of the drill bit. The angles vary depending on the type of material being drilled and the specific purpose of the drill bit. It is important to choose the correct sharpening angle based on the material you are drilling to ensure that you achieve the desired results and prolong the life of your drill bit. Here are some of the most common drill sharpening angles and the materials they are used for: 118-degree angle: This is the most common angle for general purpose drilling in materials such as wood, plastic, and soft metals. 135-degree angle: This angle is used for harder materials such as stainless steel, cast iron, and other metals. 90-degree angle: This angle is used for drilling in soft materials such as leather and rubber. 150-degree angle: This angle is used for drilling in plastics and other similar materials that are prone to melting. 60-degree angle: This angle is used for drilling in harder materials such as hardened steel and other high-strength alloys. 90/60-degree angle: This is a combination of the 90-degree and 60-degree angles, and is used for drilling in materials such as copper and brass. =============================================================
  12. Thank you, sir. What other countries have this same democracy system ?
  13. Thanks. So that is democracy ! ... Is that democracy ?
  14. Hi. Never got it clear about electoral votes, whatever that is nor whoever cast those votes. Yes, searched for it. Correct, have no interest in politics. Does it mean a candidate in U.S. elections can lose the election while having more votes count than the contender ?
  15. Thanks. I take it then like the foul smells are translated as an evolutionary warning reaction to 'not get closer' to a danger area sourcing the smell. Not as a 'you smelled it; now you are sick' And that the airborne smell molecules are too small to carry microbes 'on board' ? Thinking out of the box, if evolution has taught to stay away from foul smells, is it because that 'experience' has somehow harmed before ? Does it make sense to think that way ?
