Hi Everyone.


As you know, we've been busy adding new locations to our Atlas of Scientific Achievement above. We're now up to ~120 data points tracking everything from the invention of the first transistor to the formulation of the Big Bang theory. From the invention of the laser to the discovery of the earliest hominids in East Africa. It's been amazing watching the history of human discovery come alive before our very eyes, and we're thrilled to see that you're also getting into it, and are suggesting new locations for us to include.


(What's that? Haven't seen the Atlas yet? Well check it out! )


We thought we should share each week's suggestions with you here and see what you make of them. Which of the suggested entries below stand out to you and should be included in the Atlas? Are there any you think we should not include? Given that we're a community of electronic engineers, it's no surprise that a lot of our locations skew toward discoveries in electronics, like Jack Kilby demonstrating the first working integrated circuit. But we also want the Atlas to encompass all kinds of scientific discoveries-- electronic, physical, medical, biological, astronomical, and so on.


Our team is working hard to add your suggestions to the Atlas. So check out this week's suggestions and tell us which ones grab your attention and what you'd like to see added. And if you have any new suggestions, please add them here and we'll be sure to include them in next week's round-up. (Remember, if you include your name, we'll be sure to credit you in that location's pop-up text.)


Here are this week's suggestions.

46/16/2015The Nuclear Submarine.  As  The Historic Naval Ships Association points out, before the U.S.S. Nautilus  hit the water in 1954 submarines were really submersibles; boats that could  go underwater but not for very long. The Nautilus, built in Groton, CT. by  the Electric Boat Company and running on nuclear power, could stay underwater  for months at a time because it created its own power. Part publicity stunt,  part "˜hope you're watching, Russia,' the Nautilus even took a trip  under the North Pole ice. All of these facts have been drilled into the heads  of bored Connecticut middle schoolers being forced to visit the docked ship  on class trips.Groton, Connecticut. N 41 20.862 W 72 4.863

76/17/2015Multistage rocket - Conrad Haas/Konrad Haas
    Between 1529 and 1556, he wrote a book in German language in which he  described rocket technology, involving the combination of fireworks and  weapons technologies. This manuscript was discovered in 1961, in the Sibiu  public records (Sibiu public records Varia II 374).
    Diagram of multi-staged rocket by Conrad Haas
    In this work Haas dealt with the technical details of rocket construction,  explaining the working principles of a rocket. He described many rocket  types, including the multi-stage rocket, bundled rockets, and the idea of  modern spacecraft. His work also dealt with the theory of motion of  multi-stage rockets, different fuel mixtures using liquid fuel, and introduced  delta-shape fins and bell-shaped nozzles.
    In the last paragraph of his chapter on the military use of rockets, he  wrote (translated):
    "But my advice is for more peace and no war, leaving the rifles calmly  in storage, so the bullet is not fired, the gunpowder is not burned or wet,  so the prince keeps his money, the arsenal master his life; that is the  advice Conrad Haas gives."

146/17/2015Submarines were first built by Dutch inventor Cornelius van  Drebel in the early 17th century, but it was not until 150 years later that  they were first used in naval combat. David Bushnell, an American inventor,  began building underwater mines while a student at Yale University. Deciding  that a submarine would be the best means of delivering his mines in warfare,  he built an eight-foot-long wooden submersible that was christened the Turtle  for its shape. Large enough to accommodate one operator, the submarine was  entirely hand-powered. Lead ballast kept the craft balanced.
    Donated to the Patriot cause after the outbreak of war with Britain in  1775, Ezra Lee piloted the craft unnoticed out to the 64-gun HMS Eagle in New  York Harbor on September 7, 1776. As Lee worked to anchor a time bomb to the  hull, he could see British seamen on the deck above, but they failed to  notice the strange craft below the surface. Lee had almost secured the bomb  when his boring tools failed to penetrate a layer of iron sheathing. He  retreated, and the bomb exploded nearby, causing no harm to either the Eagle  or the Turtle.
    During the next week, the Turtle made several more attempts to sink British  ships on the Hudson River, but each time it failed, owing to the operator’s  lack of skill. Only Bushnell was really able to competently execute the  submarine’s complicated functions, but because of his physical frailty he was  unable to pilot the Turtle in any of its combat missions. During the Battle  of Fort Lee, the Turtle was lost when the American sloop transporting it was  sunk by the British.
    Despite the failures of the Turtle, General George Washington gave Bushnell  a commission as an Army engineer, and the drifting mines he constructed  destroyed the British frigate Cereberus and wreaked havoc against other  British ships. After the war, he became commander of the U.S. Army Corps of  Engineers stationed at West Point.

166/17/2015Eli Whitney (December 8, 1765 – January 8, 1825) was an American  inventor best known for inventing the cotton gin. This was one of the key  inventions of the Industrial Revolution and shaped the economy of the  Antebellum South.[1] Whitney's invention made upland short cotton into a  profitable crop, which strengthened the economic foundation of slavery in the  United States. Despite the social and economic impact of his invention,  Whitney lost many profits in legal battles over patent infringement for 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.Studied at Yale in new haven Connecticut USA

186/17/2015Dollarway Road
    The US Interstate Highway System is  listed as the largest public works project (about 47,000 miles) ever  undertaken in the history of mankind and the technique of Asphalt Pavement  over a special mix of concrete was invented here in Arkansas on what was to  be called the Dollarway Road because the cost, even including the 9 feet of  compacted gravel on each side (now called road shoulders) per linear foot was  $1.00  The Federal Government, looking  for smooth roads to connect the whole country heard about this very smooth  road surface in Arkansas that motorist from all across the country and even  from around the world were shipping their cars by rail to drive on so after  some investigation of it, copied what was invented here, and it has spread  throughout the world. The beginning of our modern day roads started with this  9 foot wide 24 miles long smooth asphalt over concrete with 9ft compacted  gravel passing lanes on each side. *The whole thing started with a bicycle  club in Little Rock asking the governor for smoother roads to ride on.*
Pine Bluff - Redfield, Arkansas    USA
    In 1913 the proposed 14 miles of newly invented road surface that began in  Pine Bluff, Arkansas grew to 24 miles long. You could drive wide open, 24mph,  here and some citizens petitioned the State to stop it because man was never  supposed to go that fast.
    Some un-retouched, un-repaired surfaces of this original 1913 road can be  found here at Dollarway Road Park in Redfield, AR. USA

256/21/2015The invention of the jet boat:
    In the early 1950s, when Sir William Hamilton began experimenting with  marine jets, he followed the lead of the most successful invention to date,  the American Hanley Hydrojet. Using a round centrifugal water pump that drew  in the water and expelled it through a steer able nozzle under the boat, he  was able to achieve an encouraging but unspectacular speed of 11 mile per  hour.
    In 1954, a slight modification to expel the jet stream above the waterline  proved the turning point in marine jet propulsion, increasing speed to 17mph  and eliminating all underwater appendages. Waterjet propulsion was at last  truly successful and the Hamilton Waterjet was born.
