Lederman, Hill book launch event April 28 at IMSA

“Quantum Physics for Poets”, by Leon Lederman and Christopher Hill, aims to make the topic of quantum physics accessible to the general public. Image: Chris Reader, IMSA.

Leon Lederman, Nobel Laureate and former director of Fermilab, and Christopher Hill, former chairman of the Theoretical Physics Department at Fermilab, will launch their new book, Quantum Physics for Poets, at the Illinois Math and Science Academy (IMSA) auditorium on Thursday, April 28.

The event will take place from 1:30 to 3 p.m., followed by a book signing until 4 p.m. Register for the event online.

Leon Lederman

The underlying motivation for writing this book was to get the next generation excited about science, Hill said.

The authors tell the story of the remarkable development of quantum theory in the early twentieth century, Hill said.

“That was such an incredible time period, 30 years that really defined the modern era for us,” Hill said. “It’s hard to appreciate that without perhaps slugging through all the graduate courses, but we’re trying to communicate that in our book.”

The book also describes the impact quantum physics has had, and will continue to have, on technological advances in society, such as in electronics and biomedicine.

Chris Hill

“We thought that the book should be amusing, it should hold your attention, there should be places in which we tell stories that have some relevance,” Lederman said.

While some might think “accessible physics” is an oxymoron, Hill disagrees, saying that the book was written for the general public.

“Even my mother said she could understand this book,” Hill said. “Physics is as much a thought system or a philosophy as it is a specific science. It underlies everything. It’s a rational way to think, and gosh, the world needs more of that.”

The free dialogue and panel discussion is part of the IMSA Great Minds Program. Copies of the book will be available at the event for $20.

Astronomers peer into the dark

From redOrbit, April 21, 2011

Astronomers from the Scottish Universities Physics Alliance (SUPA) have produced a completely new catalogue of ~15,000 groups of galaxies that gives a new insight into dark matter, the material of unknown composition that makes up a fifth of the mass of the Universe. Dr Aaron Robotham of the University of St Andrews presented the work of the Galaxy and Mass Assembly (GAMA) team in his talk on Thursday 21 April at the Royal Astronomical Society's National Astronomy Meeting in Llandudno, Wales.

Current models of the Universe predict that galaxies reside in large clumps of dark matter, commonly referred to as dark matter halos. Unlike individual galaxies, galaxy groups provide a unique environment in which to study the properties of this elusive material. Understanding the 20 percent of the cosmos comprised of dark matter is important – in comparison only 3 percent of the mass of Universe consists of 'ordinary' matter.

"The motions of the galaxies inside the groups provide a direct method for studying the properties of dark matter", says Dr Aaron Robotham who leads the group catalogue project. "Studying dark matter in galaxies is confused by normal processes such as star formation, while this unseen material dominates the motions of galaxies in groups".

ES&H Tip of the Week:

Machine shop safety is a full-time job

Typically at Fermilab, our machine shop injuries include cuts to hands, but more severe injuries can occur because of the many rotating parts in machines used in the shops and elsewhere. Just recently, a Yale student suffered fatal injuries when her hair was caught in a lathe. Because we don’t want something similar to occur here, we encourage everyone to remember the Take-Five campaign and stop before using a machine to review the machine operations and the personal protective equipment for potential dangers.

Fermilab has had a very safe record in its technical, machine, welding and carpenter shops, but that doesn’t mean safety is guaranteed. These shops have many inherent hazards that must be mitigated by guards, administrative controls and training. When working with machinery, laboratory employees and working visitors are reminded to keep their guards up.

Below are some general safety guidelines:

  • Follow the two-man rule when possible, and at all times in shops were it is required. Activities that are determined to be potentially hazardous may require another employee to be in the vicinity with range of verbal or visual contact.
  • Wear laboratory-approved safety glasses.
  • Use hearing protection when necessary. Hearing protection should be readily available to shop users.
  • Refrain from wearing loose clothing. Roll shirt sleeves above the elbows when operating rotating equipment.
  • Wear shop coats buttoned-up and aprons pulled up. Remove wristwatches, rings and any hanging jewelry.
  • Tie up long hair
  • Never leave a machine running unattended.
  • Lower air pressure back to 125 psi after using a specified-air tool. Airline pressure must not exceed 125 psi unless more is required to run a specific air tool. All air hoses are required to have nozzles with 30 psi restrictors on them.

Remember, never stop practicing your accident-prevention habits. Don’t allow years of experience to cause you to be lax in your behaviors.

If you ever encounter a situation you're unsure of or have questions concerning any shop guidelines or equipment, talk to your supervisor, Senior Safety Officer or technical subject matter expert. You can also review these guides:
