5:37 PM | Could We Use Ground-Based Lasers To Propel Rockets Into Space?
A pair of Russian scientists are proposing a radical new propulsion technique that would accelerate a rocket while in flight, by using a ground-based laser. Should it work, it could push aircraft to go beyond Mach 10. Read more...

10:51 AM | Does Max Tegmark Kill A Daughter In A Parallel World ?
The popular description of virtual particles “borrowing” energy and popping in and out of existence all the time is very misleading. There are no such processes “really happening” in the way of a naïve, classically mechanistic physicalism. Instead, all potential partial processes consistent with the observations are together what the observation supervenes on. read more

11:30 PM | There Is "Epic Movement" In A Water Drop
Directed and animated by artist Sharon Liu, Geronimo! is a whimsical, watercolor-illustrated reminder of the "epic movement we miss in every drop" of water. If you're familiar with the fluid mechanics of water droplets, you'll understand the reference; if you're not, it's high time you learned about coalescence cascades . Read more...

8:00 AM | Dan Brown Physics
Einstein’s greatest legacy- How demons and angels advanced science Thought experiments are common in theoretical physics today. Physicists use them to examine the consequences of a theory beyond that what is measureable with existing technology, but still within the realm of that what is in principle measureable. A thought experiments pushes a theory to its [...]

Pope Francis says Evolution and the Big Bang are Compatible with Catholicism You’ve probably heard, the news. Pope Francis has announced that Big Bang cosmology and evolutionary theory are compatible with Catholicism and “may even be required.” This is, of course, wonderful news. It’s evidence that science and religion are not necessarily … Continue reading → The post Pope Francis says Evolution and the Big Bang are Compatible with Catholicism appeared first […]

Sparks from Falling Water: Kelvin’s Thunderstorm The physics behind Kelvin’s Thunderstorm explained. No, it is not a practical way of generating electricity, which is why we use turbines at hydro stations.

5:45 PM | Schrodinger and Hawking in the Starbucks line
This list of entries entitled 'literary Starbucks' speculates what different well-known writers and fictional characters would order based on their personalities if they were to suddenly turn consumerist and appear in the Starbucks around the corner. Here's a sample involving "To Kill a Mockingbird" star Atticus Finch:"Atticus Finch goes up to the counter and orders the one drink on the menu that no one else was brave enough to get. As he walks out, everyone else stands up in […]

1:03 PM | Conceptual Physics Halloween Costumes 2014
A fine if somewhat intermittent tradition hereabouts has been the offering of high-concept Halloween costumes for people interested in physics, surfacing in 2010, 2012, and 2013. I’m a little too fried right now to do anything all that deep, but I’ll try to offer a few suggestions; see also these particle-physics suggestions from Symmetry magazine,…

8:00 AM | Physics in the Cloud
One thing glossed over: Joe mentions that the muons are undergoing time dilation by some factor, which allows a fraction of them to live long enough to reach earth, but in their own frame their clocks run normally. How can that work? The missing piece is that the muons see their travel as length contracted [...]

7:40 PM | How This Special Sand from Cuba Created a New Physics Phenomenon
In the year 2000, scientists officially confirmed that sand from Santa Teresa in Cuba could be used to create a new physical phenomenon known as a "revolving river." See a demonstration, and learn about the mystery of Cuban sand.Read more...

5:24 PM | Into the Woods (Synopsis)
Wandering into the woods unprepared and without a plan sounds like a terrible idea. But if you’re interested in scientific exploration at the frontiers, confronting the unknown with whatever you happen to have at your disposal, you have to take that risk. You have to be willing to take those steps. And you have to…

2:57 PM | Why do we change the clocks?
The practice of advancing clocks during summer months means that people get up earlier in the morning and experience more daylight in the evening.

1:52 PM | Particle Fever and Modern Art
As mentioned last week, I was the on-hand expert for the Secret Science Club’s foray into Massachusetts, a screening of the movie Particle Fever held at MASS MoCA. This worked out nicely in a lot of respects– it gave me an excuse to visit the newly renovated Clark Art Institute in Williamstown and check out…

1:51 PM | Tagged Dolphins Adjust by Swimming Slowly
Scientists love the data they get by attaching electronic tags to animals, but these devices can be a literal drag. For animals that fly or swim, tags can mess up their mechanics and force them to spend more energy. That’s what scientists expected to see when they studied dolphins with data loggers suction-cupped to their […]The post Tagged Dolphins Adjust by Swimming Slowly appeared first on Inkfish.

12:46 PM | Ghostly Physics (Synopsis)
You’ve no doubt heard of quantum entanglement before: the idea that if you create a mixed quantum state that consists of two particles, you can then know the properties of one by measuring the properties of the other. The odd — and counterintuitive — thing about this is that once these particles are entangled, you…

5:22 AM | Nanoscientists Among Us… as Science Communicators
“The communication of scientific findings with lay audiences has taken on heightened importance in recent years and scientists are now frequently being asked to play the role of public communicator for their work.” – Michael A. Cacciatore In a recent letter in Nature Nanotechnology, Anthony Dudo and colleagues survey nanoscientists as public science communicators. I can especially appreciate their results, because I used to be a nanoscientist myself! That was my past […]

7:40 PM | A Rare Opportunity to Watch an Electrical Tree Grow in Slow Motion
You'll often see electrical trees after lightning strikes. You can spot them in sand, in insulation, and even on very unlucky people's bodies. Generally, they form too fast for us to see them grow, which is why this video is so interesting. Read more...

1:50 PM | New CMS Results
The Large Hadron Collider at the CERN laboratories in Geneva is currently in shutdown, finalizing the upgrades that will allow it to restart next year at the  centre-of-mass energy of 13 TeV - over 60% more than the last 8 TeV run. ATLAS and CMS have collected no more proton-proton collisions since almost two years ago; yet the collaborations are as busy as ever producing physics results from the analysis of the 2012 data.Rather than focusing on any single result, below I give some […]
