The first computer I used was a real performance beast. Equipped with Intel’s 486 clocking in at 66 MHz, this machine was ready to take on whatever challenges the future would bring us. Or so I thought. The CPU clock speeds increased and soon passed 500 MHz, 1 GHz, and continued upwards. Around 2005, the top speed of the high-end processors settled around 4 GHz and hasn’t increased much since then. Why is that? I’ll explain.

How the sun, solar system, and planet Earth formed and how life began are fundamental science questions that still remain unanswered. Today, we may be one step closer to answering these questions, because the spacecraft Philae, which is aboard the Rosetta, is in the process of landing on a comet for the first time ever. I was able to interview two of the scientists involved in this project to gain insight into how Rosetta’s mission may answer these very questions.

Since 1901, the Royal Swedish Academy of Sciences has recognized significant contributions to the field of physics with a Nobel Prize award. This year’s Nobel Prize in physics was presented to a team of scientists from Japan and the U.S., recognizing their work in developing blue light emitting diodes (LEDs). Let’s take a closer look at the innovative research behind this lighting technology.

People are always asking how the performance of COMSOL Multiphysics® simulation software will improve on a parallel system, especially now that large multi-core desktop computers are relatively inexpensive and it’s easy to rent time on cloud services like the Amazon Elastic Compute Cloud™. It turns out, though, that it’s not always possible to get faster performance just by throwing more hardware at the problem. To understand why, let’s take a conceptual look at computers and the algorithms COMSOL® software uses.

After switching to a more environmentally friendly coffee maker, we recently started disposing of our coffee grounds as food waste instead of trash, here at the COMSOL office in Burlington, MA. Figuring out how to do this properly was a project on its own, but an educational one worth sharing. To pull this off, I learned about composting in my area and was intrigued by the science of composting.

In the 2012 edition of Multiphysics Simulation, we featured an article about modeling spinal cord stimulation to determine the effect that scar tissue can have on electrical current distribution during the treatment of chronic pain. Recently, the full-length paper by Beth Israel Deaconess researchers Jeffrey Arle, Kris Carlson, Longzhi Mei, and Jay Shils was published in the journal Neuromodulation.
