Iowa public land pheasant. Heavily pressured area, 25+ year old steel shot, all it takes is many miles of walking & a 10 year old GSP. Thanks Radar! #iowa #GSP #pheasant

This suggests that there could be between 125-225 billion galaxies. If we assume that these are evenly distributed across the sky, then there could be anywhere from 200 to 400,000 galaxies behind your sand grain

#JWST math: grain of sand at arm's length est of 125-225B galaxies. At 100B stars/galaxy: 100B galaxies x 100B stars/galaxy = 1.e+22 stars 10,000,000,000,000,000,000,000 stars Or Ten Sextillion or ten thousand million million million #NASAWebb @NASA #JWST_HST_SciVI

grains of sand have on average a radius of 1/16 to 2 mm (R). let's assume something at arm's length's about 75 cm away (r) so we can find how much "space" the grain of sand takes up in the sky by using [steradians] to take up (2 pi h)/r, where h is given by r(1-cos(theta)) = h

simplifying, area = 2 * pi * 1 -cos(theta) cos(theta) simply equals r/sqrt(R2 + r2) working out, we get 2.2 x 10-5 to 2.2× 10-8 rad2 for its area. Dividing this by the total area, which is 4 pi, we get values of 1.8 × 10-6 to 1.7 × 10-9 as fractions of the total area of the sky

The @US_FDA is bordering on criminal with their slow walking of #NVAX vaccine. @Novavax To consider mRNA variant boosters on mice data alone???

#VRBPAC FDA meeting on adding omicron strain to vaccines this summer/fall took interesting turn when three members said @Novavax's old-school Wuhan strain--not yet EUA'd by FDA--seems sturdier than either of mRNA vaxes. @KHNews

The anti-smoking campaign has been successful because it’s been clear, concise and leveraged visceral images that convey fact, not opinion. We need to double down on these effective tactics and recruit more authentic messengers to give context and meaning to these images.
