What graduate students do

December 23, 2020
World's smallest Christmas Tree
World’s smallest “Christmas Tree” is about the size of a DNA strand, consists of 51 individual atoms.

“A Physics student at Delft University of Technology creates world’s smallest Christmas tree made up of just 51 atoms from a perfect crystal lattice. The tree is exactly 4 nanometers tall, or 4 millionths of a millimeter.

The student Maura Willems for her graduation, uses high-powered microscope to build small structures, literally atom by atom, in order to study their quantum mechanical properties. Then changed each one’s position.”

Oh, No!

It’s not just the globe; it is the whole universe!

Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today than it was 10 billion years ago.

Here’s the link at New Atlas, but I am sure it is (fill-in-the-blank’s) fault.

Celebrate Mole Day

October 23, 2020
FAQ – Laboratory16

When I was in school, I really loved chemistry.

Well, I really loved the idea of chemistry.

Chemistry makes everything work. We are chemistry.

When it came to studying chemistry, however, I always seemed to come up short. In lab when everyone’s experiment samples turned clear, mine turned red. When everyone’s experiment turned white, mine turned black. And my experience went on from there in the same vein.

I still love the idea and the concepts of chemistry. That is why I am noting mole day today. On October 23, we commemorate Avogadro’s number:

Simply put, Avogadro’s number is the number of particles in a mole. How many particles? Exactly 6.02214085774 ×10 23 mol.

See the 10 23 in the equation above?

It is named after the Italian scientist Amedeo Avogadro

Results have finally come in. The strength of cheese spans two orders of magnitude. Interestingly this is similar to the range of strengths found in metals. Vegan Parmesan is the high strength steel of cheeses while goat cheese is like your run of the mill lead alloy.

In further studies, it has been confirmed that potatoes are harder than apples which are harder than bananas.

Where was I?

September 3, 2020

I always wondered where my town was when the dinosaurs walked the earth, when the Rockies were built, when the sea covered the middle of North America, etc.  This interactive map designed by a paleontologist answers those questions.

Interactive Map shows where your Town was 750 Million Years Ago

I could not get the interactive map to load, so go here to see where your city was 400 million years ago:  https://dinosaurpictures.org/ancient-earth#240

Inspired by a fascination with old, illustrated medical and other scientific textbooks, artist Michele Volpi turned his skills to the medium of tattooing.  Here are some examples of finely detailed designs.

Animal, vegetable or mineral . . .

March 19, 2020

In an enchanting new video titled “Waiting to Be Found,” Dan Hoopert dives into the details within Earth’s minerals. The United Kingdom-based designer highlights the sprawling crystallization process as it expands within each deposit and alters its colors. One piece even grows a sparkling mass off its left side.

Hoopert’s project is based on a 2019 article in Earth, which states that the International Mineralogical Association recognizes more than 5,000 distinct minerals, including well-known silicates and carbonates that are frequently found in masses around the world. “Most are documented based on just a few known occurrences. It’s unlikely that scientists will stumble across many new finds of singularly abundant minerals on Earth, but numerous rare minerals are probably yet to be discovered,” the article says. In the last decade, about 1,000 new species were added to the association’s growing list.

The designer brought the project to life using 3D special effects software Houdini and Redshift. For more of his imaginary explorations of natural processes, follow him on Instagram and Behance.
