  1. I'm no expert, but you should be taking this very seriously. Gloves, masks, regular washing of hands, social distancing should all be adhered too. Granted, it's easier to say than it is to do, do you even has access to face masks and gloves? I don't nor can I get any.

    The moderator Charon Y is a good person to follow on this subject. Very knowledgeable and informative. Try reading through the corona virus mega thread.

    Take care. Stay safe. ūüôŹūüŹĽ

     


  2. 'Trump says he may soon push businesses to reopen, defying the advice of coronavirus experts'

    Quote

    ‚ÄúYou look at automobile accidents, which are far greater than any numbers we‚Äôre talking about,‚ÄĚ Trump said. ‚ÄúThat doesn‚Äôt mean we‚Äôre going to tell everybody no more driving of cars.‚ÄĚ

    Sure glad I don't live in America right now. This guys an idiot.

    Antibacterial and antiviral activity are lower if no water is present. Depending on microbe or virus, maximum effectivity were observed between 60-80%. Standard disinfection in lab is usually carried out with 70%.

    What should you use to dilute it instead of water?


  3.  I'm not sure about the magical properties of Moscovium. It's seems more like science fiction rather than science fact. And if Bob Lazar says he's worked with a stable form then I don't trust him.

    it is fascinating though, I'd never heard of the 'island of stability' before.

    Quote

    There is considerable scientific speculation about the possibility of stable elements in the Island of stability. However, moscovium has been produced by two different groups, and is highly unstable, alpha decaying in less than a second to nihonium, element 113.[22]

    Good find I also saw where they found a sugar or is this the same thing? 

    Looks like the same thing. They found Ribose, a type of sugar found in RNA. Doesn't mention it in my link. Found another story that mentions it and also says;

    The team admits, however, that what they have found may instead be a polymer a broader class of molecules of which protein is a member and they are inviting further research into Acfer 086 and similar meteorites to confirm what exactly they’ve found

    I believe it was Caffa, on the Black Sea, where Mongol army besieged the inhabitants, and Venetian traders, on or about 1350, catapulting dead corpses and rats over the city walls. When the Venetians were finally able to make a break for it, they sailed west and docked in southern Italy.
    Within months Bubonic Plague had spread to most of Italy, and within years, to the rest of Europe.
    It is estimated that with the additional flare ups over the next century, the Black Death wiped out over a third of Europe''s population.

    Fuck, that's fascinating and slightly terrifying at the same time.


  6. It's an interesting video. Surprised to hear that science doesn't study UFO's. Can't really get my head around that to be honest. How can you not want to know what UFO's are. Especially Scientists.

    But it's kind of exciting if you think about it, imagine what we could learn if science really made a effort to study them. Even if they weren't aliens it would still be fascinating to find out what they are.

    You are  confused ?

    Well so am  I.

    Calcium hydroxide is  barely soluble with a solubility product  of 5.5 x 10-6

    So I make its solubility as 0.0112M at  room temperature.

     

    Did  you copy the molarities down correctly?

    Could it be a trick question?

    Sounds like the plot of a direct-to-DVD movie. Perhaps one that‚Äôs supposed to be a comedy, because the ‚Äúterrorists‚ÄĚ are incompetent¬†

    A bit off topic, but Tom Hanks would be the perfect lead. Apparently him and his wife have tested positive. Hope he recoverers, He's one of your greatest actors.


  9. I don't think it's that far fetched to be honest. Alot more effective than a suicide bombing. Easier to get it into a country than a bomb. Think of a 'lone wolf', catch coronavirus and just go around leaving your germs everywhere. 

    Dont think it would be as easy or as effective as it sounds, but it does makes me wonder. 

    100 years till the end of humanity is a being a bit pessimistic though.

    A team of researchers from Plex Corporation, Bruker Scientific LLC and Harvard University has found evidence of a protein inside of a meteorite. They have written a paper describing their findings and have uploaded it to the arXiv preprint server.

    Florida State University physicists believe they have an answer to unusual incidents of rare decay of a subatomic particle called a Kaon that were reported last year by scientists in the KOTO experiment at the Japan Proton Accelerator Research Complex.

  12. I'm not convinced. I don't think being forgetful whilst talking, especially in public, is a definite sign of cognitive decline. That video is nothing more than a blooper reel.

    And Walker Bragman is a journalist and cartoonist not a neurologist. Not what I would call a credible source of information.

     


  13. Mohamed Abdus Salam: Pakistani theoretical physicist. He won the 1979 Nobel prize with Sheldon Glashow and Steven Weinberg for their work on electroweak unification theory.

    https://en.m.wikipedia.org/wiki/Abdus_Salam#Religion

    Quote

    Abdus Salam was an Ahmadi Muslim,[36] who saw his religion as a fundamental part of his scientific work. He once wrote that "the Holy Quran enjoins us to reflect on the verities of Allah's created laws of nature; however, that our generation has been privileged to glimpse a part of His design is a bounty and a grace for which I render thanks with a humble heart."[36]

    During his acceptance speech for the Nobel Prize in Physics, Salam quoted verses from the Quran and stated:

    "Thou seest not, in the creation of the All-merciful any imperfection, Return thy gaze, seest thou any fissure? Then Return thy gaze, again and again. Thy gaze, Comes back to thee dazzled, aweary." [67:3‚Äď4] This, in effect, is the faith of all physicists; the deeper we seek, the more is our wonder excited, the more is the dazzlement for our gaze.[108]

  15. 'Is there any psychobiological benefit to throwing i the odd really simple level,  that is quick to complete'

    Personally I would prefer the levels to get progressively harder with easier bits within the levels themselves to aid progress and encouragement. A hard level followed by an easy level followed by a hard level doesn't make much sense to me.

    There's a certain satisfaction completing a hard level. Maybe instead of easy, make it more fun instead. What about bonus levels? A chance to boost your points or win some goodies that can be applied to the next level.

    Good luck with your game.

    • Researchers have¬†held individual atoms¬†and released them to interact for the first time.¬†
    • Their secret weapon is a set of three¬†optical tweezer¬†setups to hold atoms in suspension.
    • They made predictions about the few-body problem, but were surprised by their results.

     

    Quote

    ......The researchers use optical tweezers as part of their setup. Atoms can be isolated and held in place with optical tweezers, and these researchers simultaneously used three separate tweezers. Once three atoms are held in laser lock, the researchers move all three setups together and then drop two of the gates. All three atoms are then free to interact in the remaining optical tweezer setup.
