Drag was the expected answer, but despite the hint part, the actual
science part of the question was sufficiently non-specific that I
accepted "friction" and "air resistance". Not "turbulence", though;
the dimples reduce drag by *increasing* the turbulence. So, 4 for
Bruce, Dan Blum, Björn, Peter, Marc, Joshua, Jason, and Dan Tilque.
2 for Calvin.
> 2. What kind of rock is a professional curling stone made from?
Granite. 4 for Bruce, Dan Blum, Peter, Erland, Marc, Calvin, Pete,
and Joshua.

Understeer. 4 for Peter, Marc, and Calvin.

H3N2.

T cells. These are a type of white blood cell and I neglected to
require a more specific answer if that was given, so I accepted that
answer also. 4 for Bruce, Dan Blum (the hard way), Peter, Marc,
Calvin, Pete, Joshua, Jason, and Dan Tilque.

To replicate a DNA sequence. 4 for Bruce, Marc, and Dan Tilque.

Pangaea. 4 for Bruce, Dan Blum, Björn, Peter, Erland, Marc, Calvin,
Joshua, and Jason.

Gondwanaland or Gondwana, Laurasia. 4 for Bruce, Dan Blum, Peter,
Marc, Calvin, Pete, Joshua, and Dan Tilque.

Viagra (or sildenafil). 4 for Bruce, Dan Blum, Björn, Peter, Marc,

Sous-vide (or "cryovacking"). 4 for Bruce, Dan Blum, Peter, and Marc.

Caramelization. This is a type of browning, but browning may involve
other processes such as the Maillard reaction, so no points for that.

Molecular gastronomy. No points for "molecular something"!
4 for Bruce, Dan Blum, Peter, and Joshua.
