@jsshamma Is that 6 humans or 6 machines? Or 6 human machines?

[Dr Eugenia Cheng --no advice please-- @DrEugeniaCheng]

In case it needs saying again: not all mathematicians enjoy "math puzzles". So if you don't enjoy "math puzzles" that doesn't mean you're not cut out for mathematics.

@JSEllenberg The “Average”, “as much as”, and “100 to 200” seems to be the problem. The first 2 could be mean of max, 1st and 3rd gives a std dev, and any single one would be OK. But all three?

@kyledevans @TimHarford 47.23. Sounds like a good book

Happy lunar new year to all who are celebrating!

@DLeonhardt Good article in The Morning NYT today. Minor nit: "...about 110 million people...likely had the virus...Another 33 million...received...one vaccine shot." There is significant overlap between the two groups

Pretty clearly debunks "Dr" Shiva's video

[Matt Parker @standupmaths]

One of the main videos using math to ‘prove election fraud’ is Dr Shiva’s video (currently 800k views) equating a downward slope in a plot of Trump votes to votes bring stolen.

But Biden’s plot is identical: apparently their votes are stolen as well‽

Yes. Yes. Yes.

Spreadsheets anyone?

[Matt Parker @standupmaths]

Do you suffer from having to organise and analyse a set of numbers? Then Spreadsheets may be for you!

Written by me, performed by @mmaarrow, edited by @mralexgb. It's from the middle of my latest @YouTube video but is too good to hide away.

@trvrb What are the chances of positive diagnosis on days 3 and 5 in this example (or a false negative?). This would be relevant for pre-symptomatic screening strategies.

I guess they didn't like the answer from the quadratic and 4th order models...

[Jordan Ellenberg @JSEllenberg]

People with knowledge of math say "Please tell me they didn't blindly fit to a cubic and then extrapolate"

Interesting preliminary data on neutralising antibody responses in recovered COVID-19 patients. Seems there can be a wide range of antibody responses post-infection (including undetectable). But still unclear what this means for future reinfection risk. https://t.co/SNoLBNoc9p

Massachusetts grocery store workers are doing a tremendous job on the front lines every day, serving customers + making sure residents have the food they need.

This crucial work does not go unnoticed. On behalf of the Commonwealth, THANK YOU for all your work during this crisis.

@MassHHS @MassGovernor Drs think O2 is unlimited
1. Most hospital rooms not designed for ventilator O2
2. Codes only assume 25-50% of rooms will use O2 at once
3. How many days supply O2 does a hospital have?
4. Oxygen conservation devices need to be evaluated ASAP
