The Science of How Temperature and Lighting Impact Our

That means the temperature in your room, the colour of your walls and Similar to the science about sleep, paying attention to these rhythms.

No wonder I”m always complaining about being cold at work!

One thing to consider in offices that don’t have access to natural light is “daylight” bulbs – standard fluorescent tubes with a temperature rating of 5000 Kelvin, as opposed to the more standard temps of 4100K (warm white) and/or 3500K (cool white).

I think over heat is even worst than working in a cold working environments. I feel I cannot think while sitting next to the opening window and fans but 30 degrees outside at the same time….

A lot less of your energy goes towards concentration, inspiration and focus.

The Sexist History of Room Temperature

Anthony Lydgate examines how the scientific standards for thermal comfort have tended to neglect women, and how fixing them might help.

By Adrian Nicole LeBlanc By Lawrence Wright.

Like many cold-weather natives, Fanger disliked too much noticeable movement of air—what you and I would call a draft. Warmer, more thermally egalitarian offices will necessitate changes in work culture, including our notion of what an indoor climate ought to feel like. In warmer countries, though, such as Australia, air movement is a good thing: it’s a breeze. One of the godfathers of thermal comfort was a Danish engineer named Per Ole Fanger. (“This thing about draft was all a bit of a beat-up, I reckon,” de Dear said.) Rather than cooling the air, which is energy intensive, facilities managers could make it move faster.

Clo, in other words, remained static.

In a world-first, scientists have achieved 'liquid light' at room

5.23.2017 | Nathan Becker

For the first time, physicists have achieved 'liquid light' at room temperature, making this strange form of matter more accessible than ever.

"Not only to study fundamental phenomena related to Bose-Einstein condensates, but also to conceive and design future photonic superfluid-based devices where losses are compley suppressed and new unexpected phenomena can be exploited.".

"In this way, we can combine the properties of photons - such as their light effective mass and fast velocity - with strong interactions due to the electrons within the molecules," says one of the team, Stéphane Kéna-Cohen from École Polytechnique de Montreal in Canada.

The researchers say the results pave the way not only to new studies of quantum hydrodynamics, but also to room-temperature polariton devices for advanced future technology, such as the production of super-conductive materials for devices such as LEDs, solar panels, and lasers.

The scientists sandwiched a 130-nanometre-thick layer of organic molecules between two ultra-reflective mirrors, and blasted it with a 35 femtosecond laser pulse ( 1 femtosecond is a quadrillionth of a second).

A Frankenstein mash-up of light and matter.

This matter is both a superfluid, which has zero friction and viscosity, and a kind of Bose-Einstein condensate - sometimes described as the fifth state of matter - and it allows light to actually flow around objects and corners.

A lot of questions need answers.

This way to the underworld.

Physicists achieve superconductivity at room temperature

Physicists Achieve Superconductivity at Room Temperature scientists have come to realise that metals cooled to temperatures of around.

An evolutionary starting point.

But don't freak out.

"The infrared pulse had not only excited the atoms to oscillate, but had also shifted their position in the crystal as well. This in turn increased the quantum coupling between the double layers to such an extent that the crystal became superconducting at room temperature for a few picoseconds.". This briefly made the copper dioxide double layers thicker - by two picometres, or one hundredth of an atomic diameter - and the layer between them became thinner by the same amount.

A lot of questions need answers.

Physicists from the Max Planck Institute for the Structure and Dynamics of Matter have kept a piece of ceramic in a superconducting state, disproving the widely-held assumption that materials need to be cooled to temperatures of at least -140 degrees Celsius to achieve superconductivity.

However, the successful experiment is proof that such a thing is possible.".

Scientists Demonstrate "Liquid Light" at Room Temperature for the

Researchers from Italy and Canada have made liquid light at room temperatures for the first time. The work paves the way for studying quantum.

Superfluid Bose-Einstein condensates follow the rules of quantum physics instead of classical physics. Usually, they are only able to exist for fractions of a second in near absolute zero temperatures, but this work, published in the journal Nature Physics, proved that is not always necessary.

“The fact that such an effect is observed under ambient conditions can spark an enormous amount of future work,” the researchers wrote in the study, “not only to study fundamental phenomena related to Bose-Einstein condensates with table-top experiments, but also to conceive and design future photonic superfluid-based devices where losses are compley suppressed and new unexpected phenomena can be exploited.”

“Under normal conditions, a fluid ripples and whirls around anything that interferes with its flow,” Stéphane Kéna-Cohen, the Montreal team coordinator, explained in the press release.
