I just bought tickets to see David Garrett in concert later this month. I’ve been out of lab for a week and it feels weird and uncomfortable and I don’t like that. But Spring Break was nice… and cold despite being in Memphis. The city closed for three days due to the ice. -_-
They also basically cancelled Mardi Gras. D:
We got stuck at Beale street (think Bourbon St., but in Memphis) and ended up at Hard Rock Cafe. On Mardi Gras.
I was crowned ice queen because the day before I came and the day after I left it was in the 70’s (Fahrenheit).

PHYSICISTS and MATHEMATICIANS of the ANCIENT WORLD

Anaximander / Ἀναξίμανδρος(c. 610-546 BCE) is widely regarded as the world’s first physicist – the first to record his belief that nature followed fixed laws. He conducted the earliest recorded experiment, and introduced the sundial and other instruments.
Pythagoras of Samos / Πυθαγόρας ὁ Σάμιος (c. 570-495 BCE) discovered the Pythagorean Theorem: that a square laid along the long side of a triangle covers the same area as the two squares laid along the two shorter sides.
Euclid / Εὐκλείδης (c. 325-265 BCE) built up a complete description of space from a handful of axioms, such as “two parallel lines never cross.” He’s remembered as the “father of geometry,” and the particular kind of space he described, where parallel lines never cross, is now called “Euclidian space.”
Archimedes / Ἀρχιμήδης (c. 287-212 BCE) was an early scientist and engineer, maybe one of the most brilliant mathematicians of all time. He designed a number of innovative machines and discovered the principle of displacement: that the weight of an object floating in water is equal to the weight of the water it shoves aside.
Hypatia / Ὑπατία (c. 360-415 CE) was the headmaster of the Platonist school at Alexandria, where she taught mathematics and astronomy. She invented the astrolabe and perhaps the hydrometer, and wrote several major books on geometry.
Āryabhaṭa / आर्यभट (476-550) was a pioneer of mathematics and astronomy in India. He is believed to have devised the concept of zero and worked on the approximation of pi.
Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham / أبو علي، الحسن بن الحسن بن الهيثم [Latinized as Alhazen or Alhacen] (965-1040) was a mathematician, astronomer, and philosopher, sometimes known in Europe as simply “the physicist.” He invented the camera obscura and is the father of modern optics.
Wikipedia adds: “He has been described as the father of modern optics, experimental physics and scientific methodology and could also claim to be the first theoretical physicist.”

So this is how the PhD students here have labelled the microwave.
They’re not wrong. It is a radiation source.

"Umm, how can you be ‘semiaquatic’, you either are aquatic or you’re not. Don’t be greedy."
"So, I get that you’re a monotreme and everything, but do you identify more as a rodent or a bird?"
"Ugh, why do you have to be such a special snowflake. Do you and like three other species need…
It’s called hydrophobic sand.
It’s normal sand coated with a hydrophobic material (a material that does not like water). The presence of this hydrophobic compound causes the grains of sand to adhere to one another and form cylinders (to minimize surface area) when exposed to water. As soon as the sand is taken out of water, it is completely dry and flows freely.
This was originally developed to trap ocean oil spills near the shore. This would be done by sprinkling the hydrohyobic sand on floating petroleum, which would then mix with the oil and make it heavy enough to sink. The process of making this material is pretty expensive so it’s not used for removing oil spills.
The sand is made in blue, green, or red in colors but appears silvery in water because of a layer of air that forms around the sand, making it unable to get wet.

It’s called clomipramine.
