Today, Texas is living in denial. In a month, its people will be paying the price.

Back in March, when Harris County unexpectedly cancelled the Houston Livestock & Rodeo, residents were taking things seriously. SARS-Cov-2, the virus that causes COVID-19 has a slow incubation time, but the numbers don’t lie when you plot them. Slowly, new confirmation rates started growing at a slowing rate as the virus burned through the supply of infected but not yet ill people. Then, by the first week of April, the growth of new cases flattened, then actually started to drop.

Very little, and it’s mostly in the form of light shining through the door.

“Radiation” just means anything projected through space. It includes potentially harmful neutron, gamma, and x-ray radiation, but it also includes sunlight, new ideas, and the petals of flowers.

The word “radiation” does not mean “magic death cooties,” and just because a device emits radiation doesn’t mean it can hurt you without falling off a counter and hitting your foot.

A huge misconception about the SARS-Cov-2 Coronavirus is that it’s similar to seasonal fluenza. Well, both are respiratory infections (as are colds) but that’s where the similarities stop. And the more we learn about this new virus, the stranger it appears.

• The Flu’s R0 number is 1.3 whereas COVID-19 is 2-2.5, meaning it’s about twice as contagious;
• The incubation period for the flu is four days whereas COVID-19 is 14 days; meaning it can spread far and wide before it’s detected.
• The average flu hospitalization rate is 2% whereas COVID-19 is 19%; meaning that even for the young and healthy, it’s more likely to be costly and leave lasting disability.
• The flu’s case fatality rate is 0.1% whereas COVID-19 is 1-3.4%;
• Currently, there is no COVID-19 vaccine whereas there is are effective vaccines for most flu virus strains;

There is, however, one way that SARS-Cov-2 is like the flu — an infected person is most infectious before they develop symptoms. This has been known about flu for decades, and why it hasn’t influenced public health advice much during the pandemic is hard to fathom.

I will never get a change to tell D.C. Fontana what she meant to me as a little boy growing up in turbulent times, or as a grown man tempted by the writing bug. Dorothy, who wrote under the byline “D.C.” because the world isn’t what it ought to be, has died at the age of 80.

When early rocket pioneers started strapping volunteers to missiles, how did they know those volunteers would need spacesuits? Of course, in both the Soviet Union and the US, animals subject we tested first, but in fact, we already had aircraft flying almost to the edge of space before that–and aircraft flew higher than humans can survive even during World War II. How did we prepare for this environment? How did we know we needed to?

Well in fact, people had been flying in balloons since the 18th century, and some later balloon flights led to deaths. But long before this, in 1644, Torricelli described the first mercury barometer, writing “We live submerged at the bottom of an ocean of the element air.”

Torricelli and his mentor Galileo knew full well that we live on a spherical planet, but Galileo gave an erroneous explanation for the difficulties in using the suction pump to draw water up a well even though Aristotle had known that air has weight.
