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: High-pressure scientists in Bayreuth discover promising material for information technology

Researchers at the University of Bayreuth have discovered an unusual material: When cooled down to two degrees Celsius, its crystal structure and electronic properties change abruptly and significantly. In this new state, the distances between iron atoms can be tailored with the help of light beams. This opens up intriguing possibilities for application in the field of information technology. The scientists have presented their discovery in the journal "Angewandte Chemie - International Edition". The new findings are the result of close cooperation with partnering facilities in Augsburg, Dresden, Hamburg, and Moscow.

The material is an unusual form of iron oxide with the formula Fe₅O₆. The researchers produced it at a pressure of 15 gigapascals in a high-pressure laboratory...

Im Focus: From China to the South Pole: Joining forces to solve the neutrino mass puzzle

Study by Mainz physicists indicates that the next generation of neutrino experiments may well find the answer to one of the most pressing issues in neutrino physics

Among the most exciting challenges in modern physics is the identification of the neutrino mass ordering. Physicists from the Cluster of Excellence PRISMA+ at...

Im Focus: Therapies without drugs

Fraunhofer researchers are investigating the potential of microimplants to stimulate nerve cells and treat chronic conditions like asthma, diabetes, or Parkinson’s disease. Find out what makes this form of treatment so appealing and which challenges the researchers still have to master.

A study by the Robert Koch Institute has found that one in four women will suffer from weak bladders at some point in their lives. Treatments of this condition...

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...
