    Hey Hank, what about a video on magnets in space against solar wind?
    I read a NASA white paper about 1-2 Tesla dipole on L1 lagrange to protect Mars atmosphere from being stripped by the sun, should we ever try to terraform it.
    I also suggested this for Real Engineering, you could team up :-)

    Just had this thought: If Newton is defined as "the force that would give a mass of one kilogram an acceleration of one meter per second per second", and 786.83129855116 calorie [burned] equal 1 newton. Does that mean if I throw a 1 kg weight past 1m/s (assuming takes less than a second to throw it). I burned at least 786 calories?!! That can't be right? Anyone care to point out where the flaw is? Thanks.

    Unrelated to a request, I just wanted to thank the staff at SciShow and SciShow Psych for being an awesome, educational Youtube Team! I love enriching my brain with more and more knowledge from the videos that your team produce. Seeing how accessible the information you have been using to make these videos is has inspired me to one day become a scientist myself, so that I can contribute to the collective of human knowledge and maybe make life better for others one day.

Are you guys instructed to make these hand movements as part of a visual aspect or does it just happen to carrying degrees depending on the presented?

    Video Idea: Are Plesiadapiforms from the Paleocene Epoch considered in the primate order or are they proprimates? According to Jonathan Bloch's discovery, Plesiadapiforms are primate ancestors because they have very similar characteristics. However, Philip Gingerich classifies them as Proprimates because they don't have enough similarities and they have a potential relationship with the first true primates.

    Hello SciShow crew and thank you so much for all these great videos! You've already talked about blood types and transfusions. How about a video about the effects of blood donation on the donor? Benefits, risks, why males usually are allowed to donate more often than females, why you shouldn't run a marathon 5 minutes after donating blood... (This isn't really science, but I find it really weird that in some parts of the world people can be paid for donating blood. In Finland that's not allowed and I think it's good. I would hate to see somebody lie about their health just because they need money.)

    Video idea, or just a crazy thought: Would digging a trench/canal from the east coast of America to the west coast "solve the water crisis" where ever there might be a water crisis along it's path? Would the water traveling that far across the country become desalinized enough to be safe to drink? What would happen to the land in the middle of the country? Would we end up flooding a bunch of states? Which way would the water flow? Would there be a tide/rising water levels?
    Let's say the trench is 100 feet wide by 50 feet deep. Then let's theorize about a trench of a different size, maybe a mile wide by half a mile deep.

I noticed that they tend to either let it continue to drift on or send it to a collision course to some planet or object in space. Would it be possible for the NASA team to use the last bit of the life to redirect the satellites back to earth or something so it can be repurposed or salvage? I'm just curious and was wondering if anyone could answer that question...I could be asking something dumb but I just wanted to know. Thank you all for your replies in advance.

    Okay, during the solar eclipse I notice how much cooler it seemed to get because the suns rays were not getting to the earth. So, since we are facing a global warming/climate change crisis, why can't we build a orbiting solar farm to shade the earth (at least part of it) and give us power at the same time? This would give us the needed time to convert over to an electrical society and get away from fossils fuels that are causing the problem.

    You're scientists...of sorts. The way human speech works on the brain has beautifully evolved over a very long time. It has to include certain kinds of intonation, pauses and beyond a certain natural speed of delivery, it becomes increasingly difficult for the brain to process. Your presentation is done at such a rate with all pauses edited out, that it becomes tiresome and stressful to keep up concentration. This is a style that seems to be unique to YouTube material. There is also a kind of weird glottal thing going on. It's like you've all practised a received speech technique, sheep like, without really considering whether it's effective or not. I think it evolved out of the time limitations on YouTube videos that I believe is no longer in place. Try talking normally and don't edit out the gaps and pauses. Give your subscribers brains a chance to actually take in the material you're presenting. If you're not relaxed, your listeners won't be either.

    Hank, I thought you were about science and facts? What happened at Vidcon doesn't show a person that is interested in facts in the slightest, only a person that would rather be PC or assume that the woman is correct just because they are female and will jump to conclusions. You actions have seriously put your channels credibility at stake, how can I believe a person talking about science and facts that doesn't even follow what he preaches or follow his own rules? This is truly upsetting, I can no longer recommend your channels to people in good conscience :(

    So point out the flaws in someone thesis (or blatant lies) is licence to intact violence against some one at your conference. And you endorsed it, and spit out untrue statements with no backing to support it. Unsubscribed your bias is garbage. Anita put it best in her attack, "You are a garbage human" for supporting attacks on some one because they disagree with you intellectual. Unsubscribed, and anyone with integrity would too. #Garbagehumans.

    Hi Hank, I just dropped in to let you know that I find the official vidcon response to The Sark's harassment and insults towards the majority of the audience of a panel that she was part of disgusting. Not only did you blame the victim, you also erased all the victimized women from the story. Your family name is now a disgrace to humanity.

  • Archtechnician

    Im unsubbing you vids are interesting but a channel that protects bullies and even apologies to them even tho they are the aggressor (on a anti bulling panel no less) is despicable. I am sorry to the other creators of this channels videos but the way Mr Green has handled cut and dry abuse of power, bulling of paying attendees and even panel members is sickening.
    If this was reversed I am 100% sure you would still side with the wrong person. FYI being called names is harassment going to attend a talk and sitting there is not. Going after another panelist and swearing at them because you disagree with something they said is down right verbal assault.

  • Doug Reed
    Doug Reed 6 months ago

    Hey Hank, just wanted to let you know that I have to unsubscribe from all your channels, including this one. This is because you placed an openly known sociopath and cyberbully above the law at VidCon 2017 and excused her harassment and bullying of other panelists and paying attendees, while expelling one of her victims from the event. Such victim-blaming and double-standards are, to me at least, wholly deplorable. I simply cannot support a channel run by a person that acts in such a way.
    Also, I read you response to (part of) the situation. Based on the complete lack of factual evidence, objectivity and critical thought displayed therein, the decent thing to do would be to shut-down this, and any other science/academic channels you may run.
    Best wishes in the future, and best of luck becoming a rational person that is worthy of respect.

    I'm unsubbing, I subscribed to this channel because it seemed unbiased and scientific in it's methodology.
    I was shocked to hear that Mr. Green and his brother's extremely popular VidCon would not condemn and follow their own rules when it come's to harassment and all because the victim holds political views the brothers and the aggressor do not agree with.
    Disgusting behavior, when the whole world is watching and the video evidence is clear and uncut. If I cannot trust Mr. Green to tell the truth and follow the rules he's has set for his event... then why should I trust science videos he put's out.

    question, Causality vs the speed of light. causality propagates at the speed of light, but the speed of light isnt constant, so could light be slowed through a medium in which it moves slower so as to have the causality arrive before the light?
    example gravity propagates at the speed of light, if the sun disappears it would take 8 minutes before the earth started floating off into deep space, could the light be slowed (through water, air or anything that isnt the vacuum of space) so that the effect arrives before the light disappears?

    can you do a educational video about cost of preventing climate change vs the cost of climate change impact
    we have alternative sources of energy already that is getting as cheap as fossil fuels as coal so it will not cost a lot of money to simply reduce/remove fossil fuel use
    meanwhile the impact of climate change are more powerful natural disasters like storms, heavy rain, sea level rising, droughts that can cause food shortages, worldwide migrant crisis, diseases/epidemic from pollution of burning more fossil fuels, social conflicts/wars, etc and when you total the cost of them all it will be much higher
    i hope you can expand on those things i said

    I know this may not be good enough for an episode, but maybe you could explain to me what is going on?
    There is this post on Facebook that when you scroll it on your news feed, the words pop out from the background, but when stationary, they are much harder to read. It is a checkerboard pattern with words written in a light gray between the black squares. Why does motion cause the words to pop out like that becoming visible. I know it isn't changing, but scrolling causes my perception of it to change. If you do this as a vid response, maybe you could include other similar illusions. Thanks. If you need an example, I could provide a link, but I've found many popular YouTube channels auto delete comments with links, and I really want to know what is going on here.

    My girlfriend is very very very skeptic about the health benefits of garlic. Specifically whether or not it boost immune system. She says there haven't been any studies confirming it (and I wasn't able to find anything she deems credible) and we cannot agree on the matter. We both found that there have been studies showing some benefits of garlic in either preventing or battling cancer, but that isn't the same as "boosting/improving the immune system". Could you look into this question and make a video about it?

    A good question for a video: Why tires with more grip are wider if the friction equation is μ times N ?

    • Matheus M. M.
      Matheus M. M. 7 months ago

      To be honest with you VIctoria I know the answer and yours is incorrect/inaccurate. I proposed it because this question is very common when we are talking about friction at high school here in Brazil. I'm going to teach tribology ( the study of friction) for undergraduated students and some of them will answer like you... probabily... I guess.... Anyway, thank you for trying to help !

    • Victoria Tewell

      If you have a narrow tire, friction is only applied to a small surface area. In comparison, the wider the tire, the more surface for the application of friction.

      I haven't studied physics since college 18 years ago, but I wanted to give you a (probably wrong) idea in case you didn't get any other responses (since no one ever responded to my question.)
      In order to calculate the force, you should need the amount of area over which that force is being applied. If you're looking for where the size of the tire comes into play, you might want to take a look at what goes into calculating N.

    First off, I love your channel, well actually I love science thus your channel ;-)
    I have a question for you:
    when you get your DNA analysis results and goes like, 40% of this 25 % of that ... etc ? what is exactly meant by that % ?
    what is 100% ? we all know we share our DNA with all living creature for instance more than 98% with chimps so then only about 2 % identifies humans ? is that what constitutes the 100% reference ?
    How did we identified the major traits like x% European , y% sub-saharian, middle-eastern , asian ...etc?
