An infectious disease doctor writes
It seems people
get less sick if they wear a mask.
When you wear a mask – even a cloth mask – you typically are exposed to a
lower dose of the coronavirus than if you didn’t. Both recent experiments in animal models using coronavirus and nearly a hundred years of viral research show that lower viral doses usually means less severe disease.
Most infectious disease researchers and epidemiologists believe that the coronavirus is
mostly spread by airborne droplets and, to a lesser extent, tiny aerosols. Research shows that both cloth and surgical masks can block the majority of particles that could contain SARS-CoV-2. While no mask is perfect, the goal is not to block all of the virus, but simply reduce the amount that you might inhale. Almost any mask will successfully block some amount.

This is an incredible video showing what was being developed in 1968. It just took over 20 years for mice to be considered normal on a computer. Video-conferencing much longer.

The log is an interesting invention. It began with 16th-century ships – surrounded with water, no land in sight, no sense of direction, and no sense of speed. What did you have to compare your speed with anyway?
The sailors were ingenious. They used a log – a real piece of wood – attached to a string. They’d throw it in the water and use it to measure speed.
Then they’d track this speed over time, in a logbook.
That’s the origin story of log books, now known as logs.
On Wikipedia, I also learned about the origin of the term knot as a speed metric.

I frequently learn something new from any Bill Gates interview. This one on CNBC is no exception. The fact is at 11:40 but I recommend to watch the whole interview.

Just listened to an interesting podcast of searching for a song that you only remember inside your head. It’s a long one but worth a listen.
#158 The Case of the Missing Hit by Reply All
So many interviews on financial television is full of bullshit, meaningless nothingness or jargon filled inability to communicate anything useful.
Just came across this interview with Howard Marks on Bloomberg and it was amazing to hear answers that was clear and direct to the questions that were asked.
Is it a good time to get into the market? Risk is higher now because the market has been on a bull run for a long time.
Is investing like gambling? Investing relies on four factors. Information, luck, timing and skill.
What if you don’t have skill or information? In the past, mutual funds were paid over 1% in fees. However, they have shown that generally they don’t beat the market. So invest in index funds aka ETFs.
