Is It True That No Two Snowflakes Are Exactly Alike?

13.01.2012
We shovel them, we hide from them, and we rejoice when they give us an extra day’s holiday. In a Canadian winter, the snowflake is everywhere. But how do they form? What do their complex and striking shapes tell us about nature? Looking back to our childhood, is it true that no two are exactly alike?

On Wednesday, February 1, as part of Perimeter Institute’s Public Lecture Series presented by Sun Life Financial, Kenneth Libbrecht, Physics Professor at Caltech, takes us on a visual journey to expose the secret life of a snowflake. Explore how the intricate, symmetrical and magnificent patterns emerge in nature’s frozen art through a series of scientific data and spectacular photographs.

Kenneth Libbrecht knows perhaps more than anyone should about the science of snowflakes. Libbrecht is a professor and Chairman of the Physics Department at Caltech, following his PhD in physics from Princeton University. In the mid-1990s, Libbrecht’s extensive research of the molecular dynamics of crystal growth led him back to his roots in North Dakota for a detailed study of how ice crystals – the snowflake – quite literally appear out of thin air.

Kenneth Libbrecht’s lecture, entitled “The Secret Life of a Snowflake: An Up-Close Look at the Science and the Splendour of Nature’s Frozen Art” will be held Wednesday, February 1 at 7:00 PM ET in Waterloo, Ontario. Tickets will be available starting Monday, January 16, 2012.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
