Make your tree more scientific looking.

Etsy seller Eavesmade has a fine collection of science themed laser-engraved festive ornaments for your Midwinter Science Tree. Featured scientists include Carl Sagan, Charles Darwin, Rachel Carson, Gregor Mendel, Elizabeth Blackwell, Marie Curie, Johannes Kepler, Rosalind Franklin, Dmitri Medelev, Galileo, William Harvey, Stephen Hawking, Jane Goodall, Copernicus, and Alfred Russel Wallace — 20 in all!

I just bought a complete set for this year’s tree.
