In 2012, Vi Hart made this video giving "9.999... reasons that .999... = 1" She also made a video of bad proofs why .999... does not equal 1.
Fast-talking national-treasure math vlogger Vi Hart (previously) takes a statistical look at the polling data from the 2016 presidential election and concludes that the most significant divide in the country is "old vs young," which drives things like rural/urban (because young people leave failing rural areas for cities) and even racial divides.

Here's the kernel of Vi Hart's #blacklivesmatter video, on how we remember the dead: "The officers who were killed are being treated with dignity and respect as they should be. No one reported about those officers’ past infractions or how many complaints had been made against them or their family members’ criminal records." Read the rest
Like many youtubers, the incomparable, fast-talking, sharpie-doodling mathematician Vi Hart (previously) was stunned by the Orlando shooting of Christina Grimmie, a Youtube singing star who broke out into the mainstream, and who was murdered by a man who attended her public appearance.

Vi Hart and Nicky Case created a brilliant "playable post" that challenges you to arrange two groups of polygons to make them "happy" by ensuring that no more than 2/3 of their neighbors are different. Read the rest

Just in time for you to get the most out of "The Fault in Our Stars," the incomparable, fast-talking mathblogger Vi Hart's latest video is a sparkling-clear explanation of one of my favorite math-ideas: the relative size of different infinities. If that's not enough for you, have a listen to this episode of the Math for Primates podcast.
Vi Hart, the Internet's favorite manic vlogging mathematician, has released a new video in which she teams up with math artists Andrea Hawksley and Gwen Fisher, and Gwen's sister Ruth of Sweets by Ruth. The four of them bake satisfyingly precise and geometric gingerbread polygons, then build up a variety of astounding three dimensional forms by piecing them together with icing. The video is both hunger-inspiring and brain-inspiring, and is likely to be the best thing you watch this week.
Earlier this month, mathematics vlogger Vi Hart posted a ringing denunciation of the new integration of Youtube comments with Google Plus, arguing that the ham-fisted change had brought Youtube comments to an even lower low. Hart said that the new system gave precedence to people who were able to provoke lots of replies with trollish and insulting behavior, crowding out good commenters.
It's part of a wider program through which Google is attempting to drive all its users into Google Plus (largely because advertisers are willing to pay higher rates for "social" ads, this being the latest industry mania). Googlers' annual bonuses are being paid out based on Google Plus's success, meaning that across the business, Google Plus is being crammed into every possible corner . The latest Android system, KitKat, tries to force users into Google Plus accounts for sending and receiving SMSes, and makes you opt out of Google Plus about six times during setup.
When Google Plus came in, its company proponents insisted that forcing people to use their real names would improve civility. As is often the case when doctrine fails to line up with reality, they have now doubled down on their folly. If Google Plus hasn't made the Internet "civil," the problem can't be that Real Names don't work -- the problem must be that Google Plus hasn't been wedged into enough corners of the Internet.

Google has changed the commenting system on YouTube so that you need to be a Google Plus user to post; the new system uses algorithms to promote some comments above others, and has the perverse effect of making trolls more visible. Vi Hart, the incomparable math-vlogger (and a regular favorite around here) describes how Google's decision to double down on its flagging Facebook-alike G+ service by ramming YouTube users into it has made her lose faith in the service: now her regular, good commenters comments hover at the bottom of the pile, while hateful trolls whose messages generate a lot of replies are judged "good" by G+ and promoted to the top.
The promise of G+ in the beginning was that making people use their real names would incentivize them to behave themselves. It's abundantly clear now that there are more than enough people who are willing to be jerks under their real names. In the meantime, people who have good reason not to post under their own names -- vulnerable people, whistleblowers, others -- are now fully on display to those sociopaths who are only too happy to press the attack with or without anonymity.
