Turtle Shells

Ada McVean: "Daily reminder that turtles are not 'inside' their shells. They *are* their shells."

McVean elaborates:
Quick guide: mollusk shells = exoskeleton (they can often leave them) veterbrate shells (turtle/tortoise) = endoskeleton (they can't leave them, it's part of their spine)

Stricter Rules For Hawaii Visitors

More details of the mandatory 14-day quarantine for visitors to Hawaii:
The person will also initial and sign the mandatory order for self-quarantine form confirming they are aware they must self-quarantine for 14 days. By signing the legal document, they acknowledge they understand violating the order is a criminal offense and they are subject to a $5,000 fine and/or a year imprisonment.
An airport representative will collect the two forms and begin verifying their information. First, they will call their mobile phone number to confirm it rings right in front of them. If it does not ring, the person may have listed inaccurate information and is asked to verify the number. If the person refuses to provide a phone number that can be answered on the spot, law enforcement is contacted and they are subject to citation and arrest.

After the phone number is verified, an airport representative will then check the address listed for lodging. For returning Hawaii residents, the address should match their government issued ID. For visitors, the airport representative will call their hotel to confirm they have a reservation. Processing personnel have phone numbers for every hotel in the state.

Hsieh Forbes Column: Do Not Delay Urgent Medical Care Due To COVID-19

My latest Forbes piece is now out: "Do Not Delay Urgent Medical Care Due To The COVID-19 Coronavirus Pandemic".

I'm glad to be able to discuss some practical information for patients, as well as to tie our current situation back to Bastiat's famous principle of "the seen vs. the unseen."

Zoom Marriages

"Zoom marriages are now legal in New York".

As a friend noted, "Wow, so you can meet, date and now marry all online." I'm guessing there's not yet an option for online-only procreation.
 

People Delaying Emergency Care

"Patients with heart attacks, strokes and even appendicitis vanish from hospitals".

If you having a serious medical emergency, please go the the ER. Hospitals are working hard to make sure their ERs are safe. (You can always call first to make sure they are ready to receive you.)

Light Data

"Does a USB drive get heavier as you store more files on it?"

Short answer, "no". It actually gets very very very slightly lighter:
When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge. To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams. This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight. However, you would need to weigh more USB drives than exist on the planet together at once before the difference in weight became easily measurable.
