Lateral Thoughts: Voices from history

By Margaret Harris

This is the third in a series of blog posts about “Lateral Thoughts”, Physics World’s long-running humour column. Click to read the first and second posts.

As part of Physics World’s 25th anniversary celebrations, I’ve been reading through the archive of “Lateral Thoughts”, the magazine’s column of humorous or otherwise off-beat essays about physics. My goal is to get a better feel for the topics that have amused and preoccupied Physics World readers over the past quarter-century, and to understand how the community has changed.

While most Lateral Thoughts have focused on the world of physics, the archive shows that every now and then, the wider world intrudes. The results can be fascinating, sobering and sometimes even disturbing. Consider the essay “Soft zlotys for western hardware”, in which the metallurgist Jack Harris describes taking a research trip behind the Iron Curtain to Poland. “In science, as in other areas, I was struck by how little real contact there was with Russia,” Harris wrote. His Lateral Thought was published in July 1989. Two months later, Poland defied its puppet-masters in Moscow by electing its first non-communist government since the Second World War.

Personal reflections on Plutopia

By Margaret Harris

As Physics World’s reviews editor, I come across a lot of books that interest me intellectually. But with Kate Brown’s book Plutopia – the subject of this month’s Physics World podcast – my interest is personal, too.
The human side of plutopia

Brown’s book tells the story of two cities, Richland in the US and Ozersk in the former Soviet Union, that were built to house workers at the nearby Hanford and Maiak plutonium plants. Brown calls these cities “plutopias” because high wages and subsidies meant that residents enjoyed a better standard of living than their neighbours outside the secure zones. Such benefits, in turn, fostered an atmosphere of loyalty and solidarity that helped keep the plants’ horrendous environmental records under wraps.

This sounded familiar to me because my childhood had a decidedly “plutopian” flavour.  Although I didn’t grow up in an “atomic city” like Richland or Ozersk, my father worked for a defence contractor for 39 years, and his plant’s generous vacation allowance meant that we took longer holidays than most American families. We had good health insurance, too, which may have saved my life as a teenager. But after reading Plutopia and speaking to Brown for the podcast, I found myself wondering whether such benefits were a fair trade for working, as my father and thousands of others did, in a mostly windowless building that was surrounded by razor wire and contaminated with beryllium dust.

‘Mile-high’ physics

The Colorado Convention Centre where the APS is being held.

By Tushna Commissariat at the APS March Meeting in Denver

The city of Denver, Colorado has been invaded…or so I am sure the locals will feel over the next few days, as more than 9000 physicists from all over the world have arrived to take part in the APS March Meeting. I have been here in the “Mile-high city” of Denver – so nicknamed thanks to its official elevation that is exactly one mile or 5280 feet above sea level – since Sunday morning, and physics is the talk of the town as everyone descends upon the Colorado Convention Center (pictured above).

As always, there is a wide variety of interesting talks, sessions and press conferences over the next few days and I would have to clone myself multiple times to get around to all of them. Talking about cloning, though – I have just been to my first session, where Stanford researcher Patrick Hayden was taking about quantum information and asking whether or not it could be cloned in space–time. I will be speaking with Hayden later in the day, so watch this space if you would like to know more.

Physics World brings Feynman lecture to life

Physics World doodle by Perrin Ireland

Richard Feynman lecture doodle by Perrin Ireland taken from the March 2014 issue of Physics World magazine.

By Matin Durrani and Louise Mayor

Commissioned by Physics World for the March 2014 education special issue, which examines new ways to teach and learn physics, this colourful image is based on a lecture by Richard Feynman called “The Great Conservation Principles”. It is one of seven Messenger Lectures that the great physicist gave at Cornell University in the US exactly 50 years ago, a video of which can be watched here or in the digital version of Physics World.

The drawing’s creator is professional “science doodler” Perrin Ireland – science communications specialist at the Natural Resources Defense Council in the US – who describes herself as “a learner who needs to visualize concepts in order to understand them”. For people like Ireland, thinking visually or in a story-like way helps them to recall facts and explanations, which can come in very useful when trying to learn something new.

So to find out what science doodling could bring to physics, we invited Ireland to watch Feynman’s 1964 lecture and create a drawing for us – the picture above being the result. Half a century after his lecture, Feynman remains an iconic figure in physics and although we’ll never know what he would have made of Ireland’s doodle, our bet is he would have been amused.

Lateral Thoughts: a foreign country

By Margaret Harris

LT-cartoon
“The past is a foreign country; they do things differently there.”

I’ve been re-learning this lesson recently thanks to “Lateral Thoughts”, the column of humorous, off-beat or otherwise “lateral” essays that appears on the back page of Physics World each month. These articles are written by our readers and they have been part of the magazine ever since it was launched in October 1988. In fact, Lateral Thoughts is the only section of Physics World that has remained unaltered in its 25-year history.

Unaltered in its format, that is. But what about the actual content of the essays? Lateral Thoughts are not normally commissioned by members of the editorial team; instead, they’re selected from a pool of submissions sent in, unsolicited, by Physics World readers. Any shifts in style or subject matter should, therefore, tell us something about the way that the physics community has evolved over the years.

With this in mind, I began trawling through the archive of past Lateral Thoughts, looking for evidence of change. And boy, did I ever find it.

Colliding exhibits, influential researchers, edible particle-detectors and more

By Matin Durrani and Tushna Commissariat 

If you’re in the tiny minority of people whose job title says “particle physicist”, chances are you’ll have been to CERN at least once in your career to help build a detector, analyse some collision data or muse in the cafeteria over supersymmetry (or the apparent lack of it so far). But for the rest of the world, going to the Geneva lab is simply not on the agenda, which is one reason why the Science Museum in London has this week unveiled a big new exhibition devoted to CERN’s Large Hadron Collider. Entitled simply Collider, the exhibition “blends theatre, video and sound art with real artefacts from CERN” that will, say organizers, “recreate a visit to the famous particle-physics laboratory”.

‘Wizzing’ physics, fundamental prizes, galactic paradoxes and more

By Tushna Commissariat

“Wizzing” to the top of the Red Folder this week is a group of physicists at the “Splash Lab” at Brigham Young University who have studied the physics of “splashback” that occurs when people urinate. Using high-speed cameras the researchers filmed jets of liquid from a “synthetic urethra” striking toilet walls. They found that the stream of liquid breaks up into droplets when it is about 15 cm from the urethra exit. “Wizz kids” Tadd Truscott and Randy Hurd suggest that apart from sitting down on the toilet (and risk being called Sitzpinklers by their German friends), men should get nice and close when doing their business to eliminate splashback. Take a look at their video about “Urinal dynamics” above.

Writing about Oppenheimer

By Margaret Harris

Ray Monk (left) on the enigmatic J Robert Oppenheimer.

The American physicist J Robert Oppenheimer has been the subject of many biographies. It’s easy to see why. As the scientific director of the Manhattan Project, Oppenheimer presided over one of the most important events of the 20th century: the development of the first atomic weapons during the Second World War. Not long afterwards, he became a prominent victim of another key moment in history: the anti-communist “red scare” that swept the US during the 1950s. And on a personal level, he was a learned and cultured man – one who quoted his own translation of the Hindu scripture Bhagavad Gita (“Now I am become death, the destroyer of worlds”) when asked how he felt after the first test of the atomic bomb.

Do you recognize this antique scientific instrument?

Do you know what this is? Click on image for larger version. (Courtesy: Jean Barrette)

By Hamish Johnston

Last week I promised readers a genuine mystery – and here it is. Do you know what this piece of apparatus was used for?

It currently resides in the McPherson Collection of physics instruments at McGill University in Montreal and its purpose has long puzzled curator Jean Barrette – who I spoke to when I was in Canada recently.

The device looks like it is designed for bench-top use and Barrette believes that it was used to study gases. Inside the cylindrical section with the half-moon window there is another small cylindrical part that can move. The small cylindrical extension to the right of the main component is an electrode input to bring high voltage inside the chamber.

“Any idea on the purpose of the instrument would be greatly appreciated,” said Barrette.

There must be a physicsworld.com reader out there who knows what this is. Please let Jean and I know by leaving a comment below.

What happened to nuclear electrons?

By Hamish Johnston at the 2013 CAP Congress in Montreal

Sometimes I think that physicists can dwell too much in the past. Scientific papers, for example, often begin with a potted history of the field and it’s only in the second page that something new is mentioned.
