Series of New Posts: Lectures, talks, podcasts, etc…

I will be starting a regular series of posts of lectures, talks, podcasts, etc. If you have requests for topics, please feel free to comment on this post or send me a message via the contact links. The first of these posts is below:

On Oct. 7, 2015, Perimeter Institute Director Neil Turok opened the 2015/16 season of the PI Public Lecture Series with a talk about the remarkably simplicity that underlies nature. Turok discussed how this simplicity at the largest and tiniest scales of the universe is pointing toward new avenues of physics research and could lead to revolutionary advances in technology.

Why a NASA spacecraft could bounce, crunch or sink on icy Europa

Why a NASA spacecraft could bounce, crunch or sink on icy Europa

Sometime in the early 2030s, NASA hopes to attempt a landing on Jupiter’s moon Europa. A four-legged spacecraft would descend towards the icy surface, ready to hunt for signs of alien life in a buried ocean.

Landing on Jupiter’s moon in search of alien life won’t be easy.

Transparent silver: Tarnish-proof films for flexible displays, touch screens

Transparent silver: Tarnish-proof films for flexible displays, touch screens

University of Michigan researchers have created a transparent silver film that could be used in touchscreens, flexible displays and other advanced applications. L. Jay Guo, professor of electrical engineering and computer science, holds up a piece of the material. Credit: Joseph Xu/Michigan Engineering.

The thinnest, smoothest layer of silver that can survive air exposure has been laid down at the University of Michigan, and it could change the way touchscreens and flat or flexible displays are made.

LHCb observes an exceptionally large group of particles

A typical LHCb event fully reconstructed. Particles identified as pions, kaon, etc. are shown in different colours. (Image: LHCb collaboration)

The LHCb experiment at CERN is a hotbed of new and outstanding physics results. In just the last few months, the collaboration has announced the measurement of a very rare particle decay and evidence of a new manifestation of matter-antimatter asymmetry, to name just two examples.

The image above shows the data (black dots) of the reconstructed mass distribution resulting from the combination of the Ξc+ and K- particles. The five particle states are the five narrow peaks standing out from the distribution of data. (Image: LHCb collaboration)

Possible signature of dark matter annihilation detected

A false-color image of the anomalous gamma-ray emission from the central region of the Milky Way galaxy; this emission is suspected of coming from dark matter annihilation. In this image, the emission from conventional sources has been subtracted from the total. The region covers roughly five degrees; the brightest emission is colored red and faintest blue.

Physicists investigate the structure of time…

Although in theory it may seem possible to divide time up into infinitely tiny intervals, the smallest physically meaningful interval of time is widely considered to be the Planck time, which is approximately 10-43 seconds. This ultimate limit means that it is not possible for two events to be separated by a time smaller than this.
