The text you are currently reading is crisp and clear thanks to Turner Whitted, a computer scientist at NVIDIA. While working at Microsoft in 2000, he invented the ClearType algorithm that uses shades of grey to smooth text pixels and make letter boundaries clearer. Modified versions of this algorithm are used practically everywhere from mobile phones and smartwatches to laptops.

Why didn’t the Dog Star laugh at the joke? If you were in science quad last weekend (October 17th) and asked one of the Keck Northeast Astronomy Consortium (KNAC) presenters, you would likely have gotten a chuckle and a response that “it was too Sirius.” KNAC, a collaboration of eight liberal arts colleges in New England (Colgate University, Middlebury College, Vassar College, Wesleyan University, Haverford College, Swarthmore College, Wellesley College, and Williams College) funds summer research opportunities for astronomy students. The annual symposium, which rotates between the eight institutions, was hosted at Williams this year with 32 student speakers and 9 poster presentations.

Student Committee Builds Community Spirit Among Biology Majors

By Elizabeth Jacobsen ’16

It’s an exciting time to be a biology major.

This year the Biology Majors Advising Committee (BMAC) is redefining what it means to be a Biology major or prospective Biology major at Williams. BMAC hopes to build a unique sense of community among those interested in biology through an academic year of biology-related social events.

Nancy Piatczyc’s Microscopic World

By Meagan Goldman ’16

This article was inspired by Art of Science, an initiative to gather and exhibit scientific images from students, faculty, and staff. For more information, visit the Art of Science site.

“It’s endlessly fun looking at these things,” says Nancy Piatczyc while enlarging a black and white image on her computer. As the image focuses, striations appear. Without context, it might be difficult to identify what it shows: a tiny fragment of wood magnified thousands of times by a scanning electron microscope (SEM). The wood is from a ship, likely British, that sank near the New York harbor around the time of the Revolutionary War. The SEM images will help biology professor Hank Art identify the wood from which the ship was built.

Q&A: Matt Carter talks Grad School, Papers, and Effortless Perfection

By Meagan Goldman ‘16

Matt Carter’s contagious enthusiasm makes it easy to wake up for his 9 a.m. physiology class. Passionate about biology – and more specifically, neuroscience – Matt can make any lecture or discussion exciting. Last week, I sat down with him to learn about his personal experiences in the world of science. Here he divulges what he thought about neuroscience grad school and what it’s like to write a real scientific paper. Finally, he gives his opinion on the Williams myth of effortless perfection.

Ask a Biology Student: What is Energy?

This post concludes the “Ask a Science Student” series. For previous responses, see chemistry, physics, and astronomy.

Ask a Science Student, Part 4: Biology

By Meagan Goldman ’16

Biology deals with energy on both a macro level – the cycling of energy through ecosystems – and a micro level – the energy required for biological processes. Energy in an ecosystem comes initially from the sun. Primary producers, plants and cyanobacteria, convert the sun’s electromagnetic energy into chemical energy, stored in the bonds of compounds like glucose and ATP. Energy is then passed to consumers and eventually, when organisms die, to decomposers.

Ask an Astronomy Student: What is Energy?

This is the third installment in  our “Ask A Science Student” series. For the previous responses, see chemistry and physics.

Ask a Science Student, Part 3: Astronomy

By Marcus Hughes ’18

Astronomy deals with a tremendous scale of energy, from the Cosmic Microwave Background – the 2.7 kelvin echo left from the Big Bang – to hyper-luminous quasars – compact centers of galaxies related to black holes that release 4 trillion times as much energy as our Sun. Astronomy even has not yet understood types of energy like dark energy, a repulsive energy causing the universe to expand faster, literally changing the fate of the universe. When most people think of energy in astronomy, they think of stars, but dark energy makes up 70% of the total mass-energy in the universe. At its simplest, energy is just the capacity to do work; i.e. the capacity for a force to displace an object.

Ask a Physics Student: What is Energy?

Today we continue our “Ask A Science Student” series. For the previous response, click here.

Ask a Science Student, Part 2: Physics

By Matt Radford ’16

Energy has many different forms. Electrical, thermal, and mechanical kinetic energy are all forms associated with moving objects. Potential energy is dependent on an object’s position in a field, such as apples hanging in a tree, or an object’s position relative to its parts, such as a drawn longbow. An apple also has digestible energy, usually measured in calories. Other units of energy commonly found in day-to-day life include the watt-hour, which probably shows up on your electricity bill, and the British Thermal Unit, which is likely mentioned on any air conditioning unit.

Ask a Chemistry Student: What is Energy?

An alum from the class of 2010 emailed us about a month ago and told us he ran a Williams science publication (coincidentally also called the ScientEphic!) when he was a student here. We took a look at some of their old publications and enjoyed their section called “Ask A Science Major.” So The ScientEphic is beginning a series based on that section. We asked students from four departments – chemistry, physics, biology, and astronomy – to explain the concept of energy. We’ll publish their responses over the next four days.
