Freezing Bubble
A soap bubble exposed to very cold temperatures (-25°C/-13°F) will quickly freeze as ice crystals form and coalesce into an icy sphere. The intricate detail of the expanding crystals can easily be seen as the liquid water transitions to its solid state.

Back in the 1960s, the linguist and political activist Noam Chomsky claimed that the human brain is hardwired with an innate understanding of language. This became known as the Universal Grammar theory, and was offered as an explanation of the speed at which children tend to learn their first language. Genetically, the human mind is predisposed to making sense of words and arranging them in a logical sequence as we overcome the initial disorder of learning a language.

Nice letters to the editor observation from the LA Times...
"To the editor: This latest attempt by Senate Republicans to take healthcare away from tens of millions of Americans brings to mind the words that U.S. Army attorney Joseph Welch directed toward Sen. Joseph McCarthy about his allegations of communism in the Army.
Welch’s words apply today to Republican senators:
“Until this moment, senator, I think I have never really gauged your cruelty or your recklessness…. Have you no sense of decency, sir? At long last, have you left no sense of decency?”
John F. Rossmann, Tustin"

#PHP: The Right Way is an easy-to-read, #quick #reference for PHP popular #coding standards, links to authoritative #tutorials around the Web and what the contributors consider to be best practices at the present time. There is no canonical way to use PHP. This website aims to introduce new PHP #developers to some topics which they may not discover until it is too late, and aims to give seasoned pros some fresh ideas on those topics they’ve been doing for years without ever reconsidering. This website will also not tell you which tools to use, but instead offer suggestions for multiple options, when possible explaining the differences in approach and use-case.

The NFL did not recruit a single player based on his opinion of anything. Therefore paying them while they wear the uniform and make a statement is wrong. They are prohibited from certain end-zone celebrations, not allowed to do commercials in uniform, so why on earth do they allow this disrespect to our flag? They will let the armed services fly over the stadium and hold flags. There is a simple solution that I have said several times and even sent to the NFL. Play the National Anthem before the players take the field. This denies NO ONE their right to free speech/protest. If these players want to not stand for the anthem, let them go to a local football game in their regular clothes and do it.

A dust-bound supermassive black hole [artist's impression]
This artist's impression shows the dust torus around a super-massive black hole. Black holes lurk at the centres of active galaxies in environments not unlike those found in violent tornadoes on Earth. Just as in a tornado, where debris is often found spinning about the vortex, so in a black hole, a dust torus surrounds its waist. In some cases astronomers can look along the axis of the dust torus from above or from below and have a clear view of the black hole. Technically these objects are then called "type 1 sources". "Type 2 sources" lie with the dust torus edge-on as viewed from Earth so our view of the black hole is totally blocked by the dust over a range of wavelengths from the near-infrared to soft X-rays.
While many dust-obscured low-power black holes (called "Seyfert 2s") were known, until recently few of their high-power counterparts were known. The identification of a population of high-power obscured black holes and the active galaxies surrounding them has been a key goal for astronomers and will lead to greater understanding and a refinement of the cosmological models describing our Universe.
The European AVO science team led by Paolo Padovani from Space Telescope-European Coordinating Facility and the European Southern Observatory in Munich, Germany, has discovered a whole population of the obscured, powerful supermassive black holes. Thirty of these objects were found in the so-called GOODS (Great Observatories Origins Deep Survey) fields. The GOODS survey consists of two areas that include some of the deepest observations from space- and ground-based telescopes, including the NASA/ESA Hubble Space Telescope, and have become the best studied patches in the sky.
In the illustration the jets coming out of the regions nearest the black hole are also seen. The jets emerge from an area close to the black hole where a disk of accreted material rotates (not seen here).

Saturn: Shadow Art | NASA Cassini Mission
Assembled using RGB filtered images of Saturn taken on November 7, 2004.
The Cassini mission was a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of Caltech in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

Apple Watch Series 3 unboxing - Apple launch day came and went, but while consumers were probably buzzing around to check out and potentially buy the new iPhones, the Apple Watch Series 3 was also quietly released. While smartwatch sales have been tepid at best, Apple's option continues to stay at the top of the charts – even against other standard watches. With this latest iteration, we see the introduction of cellular connectivity, which was something sorely lacking since its introduction...
