13 comments> Having them memorized and at your fingertips is great for sanity checking ideas.
This is essentially the reason. There are certain idea pathways you simply cannot traverse if you constantly need to check specific values. And I think that it might be possible that your subconscious simply won't "give" you an idea until you have specific facts memorized.
Just think how much more difficult your life would be if you had no concept of a kilometer/mile, and constantly needed to do the math to check how far something is in... meters/yards, or something.
It's also a good joke opportunity, but for the link above it's not a joke.
Where I work it's about $2 a day to house a cage of 5 mice. It's about $30 a mouse if you get C57BL/6NJ's from Jackson: https://www.jax.org/strain/005304
So more like $150 for 5 mice and $800 to house for a year.
Another good one to know if the size of antibodies (10-12 nm).
For example, is it better to remember by rote all the amino acids or is it better to reason which is which be the quantum mechanics involved in the different bonding groups?
Most in biochemistry go with the 2nd option....and succeed.
A quick search didn't bring up an already existing one :(
Lol.
