“In a recent paper titled “The Scientific Case for Brain Simulations,” several HBP scientists argue that big simulations “will likely be indispensable for bridging the scales between the neuron and system levels in the brain.” In other words: Scientists can look at the nuts and bolts of how neurons work, and they can study the behavior of entire organisms, but they need simulations to show how the former creates the latter. The paper’s authors draw a comparison to weather forecasts, in which an understanding of physics and chemistry at the scale of neighborhoods allows us to accurately predict temperature, rainfall, and wind across the whole globe.”

https://en.wikipedia.org/wiki/Harald_Bluetooth

“The first documented appearance of Harald’s nickname “Bluetooth” (as blatan; Old Norse *blátǫnn) is in the Chronicon Roskildense (written ca. 1140), alongside the alternative nickname Clac Harald.[5] Clac Harald appears to be a confusion of Harald Bluetooth with the legendary or semi-legendary Harald Klak, son of Halfdan. The byname is given as Blachtent and explicitly glossed as “bluish or black tooth” (dens lividus vel niger) in a chronicle of the late 12th century, Wilhelmi abbatis regum Danorum genealogia.[6] The traditional explanation is that Harald must have had a conspicuous bad tooth that appeared “blue” (i.e. “black”, as blár “blue” meant “blue-black”, or “dark-coloured”). Another explanation, proposed by Scocozza (1997) is that he was called “blue thane” (or “dark thane”) in England (with Anglo-Saxon thegn corrupted to tan when the name came back into Old Norse).[7]”

The material he’s describing is Vantablack – the blackest black ever created. It was developed by a company called Surrey NanoSystems (SNS), whose laboratory is housed in a single-storey, pre-fab block in a dreary business park near the port at Newhaven, on Britain’s south coast. Vantablack is made from carbon nanotubes (“Vanta” stands for “vertically aligned nanotube array”). Each tube is just a few nanometres thick and a few hundred nanometres tall – that is, just a few billionths of a metre.

So it was in this dark night of despair that Holmes told members of the media and the science community she would finally be opening up about Edison, her one-drop blood analysis technology 11 years in the making. Hundreds of scientists lined up at the American Association for Clinical Chemistry this week in the hopes of finally getting a behind-the-scenes look at the secret machine. Instead, they got an introduction to an entirely new product — an all-in-one Zika-detecting tabletop miniLab.

Stop Letting Modern Distractions Steal Your Attention

Making yourself inaccessible from time to time is essential to boosting your focus.

This kind of task switching comes with a cost. It’s called attention residue, a term established by Sophie Leroy, a professor at the Bothell School of Business at the University of Washington. In a 2009 study, Dr. Leroy found that if people transition their attention away from an unfinished task, their subsequent task performance will suffer. For example, if you interrupt writing an email to reply to a text message, it will take time to refocus when you turn your attention back to finishing your email. That little bit of time of adjusting your focus — the residue — compounds throughout the day. As we fragment our attention, fatigue and stress increases, which negatively affects performance.

At the very least, she said, start leaving your phone behind during certain periods of the day, and perhaps establishing no-phone zones in your house or workplace. Treat it as an experiment: Try things and see what makes you feel good, she said.

What are the 7 fundamental units?
The SI system, also called the metric system, is used around the world. There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd).

The Challenge Lock is in the Science Museum in London. An examination of the lock shows that it has been rebuilt since Hobbs picked it. Originally it had 18 iron slides and 1 central spring; it now has 13 steel slides, each with its own spring.[3]

The maker of H1 to H4

Harrison’s last home was 12, Red Lion Square, in the Holborn district of London.[23] There is a plaque dedicated to Harrison on the wall of Summit House, a 1925 modernist office block, on the south side of the square. A memorial tablet to Harrison was unveiled in Westminster Abbey on 24 March 2006, finally recognising him as a worthy companion to his friend George Graham and Thomas Tompion, ‘The Father of English Watchmaking’, who are both buried in the Abbey.

Today the restored H1, H2, H3 and H4 timepieces can be seen on display in the Royal Observatory at Greenwich. H1, H2 and H3 still work: H4 is kept in a stopped state because, unlike the first three, it requires oil for lubrication and so will degrade as it runs. H5 is owned by the Worshipful Company of Clockmakers of London, and was previously on display at the Clockmakers’ Museum in the Guildhall, London, as part of the Company’s collection; since 2015 the collection has been displayed in the Science Museum, London.

One of the most striking differences between the Stones and the Beatles is that the Beatles split up after a mere seven years at the top, whereas the Stones are still going. One startup flashed brightly and burned out; the other established itself as a long-running corporation.

“19. The new Gmail has some noteworthy keyboard shortcuts that can save you time and make it easier to get around: Pressing “b” when you are viewing a message or have selected a message in your inbox will let you snooze it; holding down Shift and then pressing “t” will open up the Tasks panel and add your currently open or selected message as a new item; and pressing “g” and then “k” will open up the Tasks panel, regardless of what else you’re doing. (Just be sure you’ve activated the keyboard shortcuts option in the “General” section of Gmail’s settings first.)

20. Remember Gmail Labs? That’s gone in the new Gmail, but you can find many of the same options in a newly added “Advanced” section within the site’s settings. Click the gear icon in the upper-right corner of the screen, select “Settings,” then select the “Advanced” tab at the top of the screen. Useful features such as templates, custom keyboard shortcuts, and the ability to turn on an Outlook-like preview pane await.”
