The role that Whitney played in early American technology has been debated, however. Whitney’s work in making muskets from a number of interchangeable parts once identified him as the sole originator of the idea. But tests on a collection of Whitney muskets indicate that all their parts were not interchangeable.

Eli Whitney (December 8, 1765 – January 8, 1825) was an American inventor best known for inventing the cotton gin. … Thereafter, he turned his attention into securing contracts with the government in the manufacture of muskets for the newly formed United States Army. He continued making arms and inventing until his death in 1825. “}}

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]

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.”

Genome-wide association studies (GWAS) have enabled significant progress in the past 5 years in investigating genetic susceptibility to lung cancer. Large scale, multi-cohort GWAS of mainly Caucasian, smoking, populations have identified strong associations for lung cancer mapped to chromosomal regions 15q [nicotinic acetylcholine receptor (nAChR) subunits: CHRNA3, CHRNA5], 5p (TERT-CLPTM1L locus) and 6p (BAT3-MSH5). Some studies in Asian populations of smokers have found similar risk loci, whereas GWAS in never smoking Asian females have identified associations in other chromosomal regions, e.g., 3q (TP63), that are distinct from smoking-related lung cancer risk loci. GWAS of smoking behaviour have identified risk loci for smoking quantity at 15q (similar genes to lung cancer susceptibility: CHRNA3, CHRNA5) and 19q (CYP2A6).

This was pioneering stuff for the 1890s. Atwater eventually concluded that a gram of either carbohydrate or protein made an average of four calories of energy available to the body, and a gram of fat offered an average of 8.9 calories, a figure later rounded up to nine calories for convenience. We now know far more about the workings of the human body: Atwater was right that some of a meal’s potential energy was excreted, but had no idea that some was also used to digest the meal itself, and that the body expends different amounts of energy depending on the food. Yet more than a century after igniting the faeces of Wesleyan students, the numbers Atwater calculated for each macronutrient remain the standard for measuring the calories in any given food stuff. Those experiments were the basis of Salvador Camacho’s daily calorific arithmetic.

“A lot of things that take up mental energy, waste time, and rarely move you toward your goals can easily be eliminated if you apply the Eisenhower Principle. It’s a simple decision-making tool you can use right now. It’s meant to help you question whether an action is really necessary.
…
You can only benefit from the Eisenhower Method if you can commit yourself to making radical categorization of your daily tasks. This Method requires that you group your tasks and activities into four priorities.
Priority 1 tasks are both urgent and important.
Priority 2 tasks are important but not urgent.
Priority 3 tasks are urgent but not important.
Priority 4 tasks are neither urgent nor important”
