  1. For programmers 1+1=10.. https://en.wikipedia.org/wiki/Binary_number So, we should ask "in which numeral system?" https://en.wikipedia.org/wiki/Numeral_system
  2. He didn't ask, he made the statement in the thread title ("The math is inconsistent!")..
  3. Looks like puzzle of some kind. Search net for the Mohs scale, lookup mineral with 6, lookup 2, and deduce what kind of mineral it is.
  4. Are you referring to my post? (would be easier if you'd use @ Sensei ) It was math. No language was used. It was mathematics. The things with non-zero probability happens. Sometimes.
  5. If the probability of something occurring is 99%, why do you think it will be your preferred 1%? If the probability of something occurring is 1%, why do you think it will be your preferred 99%?
  6. The V.P. is waiting for the appearance of a weak Republican, conservative, pro-Russian, POTUS.. who will cut expenditures to Ukraine and/or Europe and/or NATO ("dissolve NATO"). So far, the victims are Chechnya, Georgia, Ukraine #1, Syria, Ukraine #2.. The aim is - to merge Transnistria with Odessa, with Crimea and the Kherson region, Melitpol, Mariupol, and regions of eastern Ukraine with Russia.. So basically surround the rest of Ukraine with "Russian lands".. From which an attack on the rest will come in the next "wave"..
  7. Abortion is a private matter. Sad thing if done, but sometimes it is required to save a woman's life. Without abortion, the leading cause of death for women age 50 and under, would be ectopic pregnancy, as it was in the past and is in 3rd world countries in Africa. https://www.google.com/search?q=ectopic+pregnancy+rate 19.7/1000 * 100% = ~ 2 %, one per fifty (if somebody have no math skills) (i.e., greater chance of a woman dying of a pregnancy/child than in a fatal car accident in her lifetime) Contraception is also a private matter. The child should have people who want to be parents in the first place. Who are mature and educated enough to teach the child.
  8. Get ball-n-stick model and build 3D model of this molecule and you should see.. Every chemistry student should have it. (I 3D printed my own versions)
  9. Make your own sandblaster.. (I would design and 3D print the whole thing he has in hand)
  10. Electron has charge Q = -1e = -1.6021766x10^-19 C For me, there is no problem. When talking to a non-English speaker, we have to take this into account.
  11. I think you have this one incorrect. 1.6 x 10-19 Joules is the energy of one electron volt (ev) 1,6 in some countries mean 1.6 in English.. https://en.wikipedia.org/wiki/Decimal_separator Q = e = 1.6021766x10^-19 C is perfectly fine. https://en.wikipedia.org/wiki/Elementary_charge
  12. https://www.reuters.com/business/russian-crude-is-more-reliant-india-china-signs-peak-russell-2022-08-09/
  13. Without the attack on Ukraine, there would not have been this (and thousands of other) tragic accidents and senseless deaths.. 100% V.P. responsibility. V.P. soldiers are also attacking from Belarus, Transnistria, Crimea and warships at sea.
  14. I am announcing this. Who would intentionally waste a precious rocket on a village farm and farm vehicles..
  15. Unintentionally. It was 3 kilometers from the border line.
  16. ....the easier with a mouse than with a cat....
  17. Which can be easily disqualified by looking at people with mental problems or other inabilities.. Their subjective reality might be different than yours.. ps. You don't know how some person (any person, including your family and friends), animal or other thing (A.I.?) look at this world..
  18. WiFi uses 2.4 GHz and 5 GHz (with 20 and 40 MHz channel widths) NFC/RFID use 13.56 MHz. https://en.wikipedia.org/wiki/Near-field_communication https://en.wikipedia.org/wiki/Radio-frequency_identification (I suggest reading Wikipedia)
  19. ..and you should write "free neutron". Neutrons bound in nuclei can also decay by double beta decay (rarely double beta decay neutrinoless) e.g. Uranium-238 into Plutonium-238 (it is rare decay mode). https://www.google.com/search?q=Uranium-238+double+beta+decay
  20. Sensei replied to iNow's topic in Politics
    ..they are like zombies due to toxic levels of ethanol..
  21. A man-built fusion reactor uses tritium and deuterium (this is one of the most efficient reactions). But tritium cannot be produced in advance and stored. It cannot be collected somewhere. It has half-life 12.32 years. To split lithium into tritium, you need a free neutron. Where can the free neutron be obtained? In traditional nuclear reactors, of course.. A country that wants to be self-sufficient, and create fuel for nuclear fusion, must also have traditional nuclear reactors.
  22. ..not without a reason V.P. soldiers attacking Kiev in February-March had mobile crematoria with them... They wanted to exterminate the Ukrainian intelligentsia and politicians, and vaporize them, to have no trace of it..
  23. https://www.google.com/search?q=noble+gas+discharge+tubes (and click Image mode) On the right are pictures of various noble gases glowing in discharge tubes: https://en.wikipedia.org/wiki/Noble_gas If you want to verify this more rigorously, get a prism and split it into spectral lines. ps. Your HV is not steady - build Cockcroft-Walton generator and/or Marx generator. 110/230 VAC -> DC -> high-frequency AC (timer 555?) -> CW generator -> discharge tube
  24. "You seem easily confused".. Someone gave an up-vote because of a humorous video that fits perfectly with this discussion with the OP.
  25. When you will learn to write full length sentences so they are not ambiguous? ps. Down vote? Really?
