No score for me.Greg Bernhardt said:Something appears to be broken. Anyone not getting a score when you press submit?
Maybe I'm the one to blame. If so, then I discovered a bug. I think I had been first who entered the quiz, ran shortly over it, and then wanted to know the results without doing the quiz and hit "submit" on an empty list. As a result, the first question had vanished, so I had to refresh to get it back.Greg Bernhardt said:Something appears to be broken. Anyone not getting a score when you press submit?

I hate AJAX. It's a nightmare to debug and update ...Greg Bernhardt said:There is an issue with the AJAX submission thread. I have reverted to POST and it works again. Enjoy! Post those scores!
doh! Can you see it on the Insights homepage?Ygggdrasil said:The quiz's header graphic is not visible on a mobile browser.
I added the image to the question, good luck!Wrichik Basu said:Header graphic is not visible. I see this with desktop view enabled in chrome android:
Yes I will correct, thanks!TeethWhitener said:Question 12 says "Since June 2018, the US Patent Office has issued… patents." The answer is given as 10 million. Seeing as how the 10 millionth patent was granted in June 2018 (228 years after the first patent was granted), I seriously doubt another 10 million have been granted in the last 5 months. Did the question mean "As of June 2018...?"

fresh_42 said:I protest against Edison. IMO Bouly (patent 1892, acc. 1893) resp. the Lumières (1894, renewed Bouly's patent, demo 1895) were first, maybe Anschütz (1885, 1894) or Reynaud (1892), but not Edison (1894).
Edison's patent on the kinetoscope was granted in 1897 with "Application filed August 24, 1891. Serial No. 403,534. "https://en.wikipedia.org/wiki/Thomas_Edison#Motion_pictures said:Edison was also granted a patent for the motion picture camera or "Kinetograph". He did the electromechanical design while his employee W. K. L. Dickson, a photographer, worked on the photographic and optical development. Much of the credit for the invention belongs to Dickson.[43] In 1891, Thomas Edison built a Kinetoscope or peep-hole viewer. This device was installed in penny arcades, where people could watch short, simple films. The kinetograph and kinetoscope were both first publicly exhibited May 20, 1891.[79]
https://en.wikipedia.org/wiki/Cinematograph#Invention said:Louis Lumière worked with his brother Auguste to create a motion-picture camera superior to Thomas Edison's kinetograph, which did not have a projector. The Lumières endeavored to correct the flaws they perceived in the kinetograph and the kinetoscope, to develop a machine with both sharper images and better illumination.
At least the French patent was seemingly granted earlier:anorlunda said:Edison's patent on the kinetoscope was granted in 1897 with "Application filed August 24, 1891. Serial No. 403,534. "
https://de.wikipedia.org/wiki/Léon_Guillaume_BoulyLéon Guillaume Bouly (* 1872, † 1932) is accepted as a French inventor, who was the originator of the name Cinématographe. On February 12, 1892, under the name of the application filed for a patent on an "appareil reversible de photograph et d'optique for the analysis and the synthesis of the mouvements, the Le Cynématographe Léon Bouly". It came to the French State Patent, number 219'350. On December 27, 1893, a change was made to the name of his apparatus: Cinématographe.
The Cinématographe works with paper and roll film without perforation on the principle of the clamp. The film drive is accomplished with a segmented roller opposite full roller.
When in 1894 the annual fee for the patent had not been paid, the term Cinématographe became common property and in the following year reserved for the brothers Lumière.
https://de.wikipedia.org/wiki/Ottomar_Anschütz + GoogleIn the summer of 1886 Anschütz was commissioned by the Prussian Ministry of War to "take chronophotographies of riders and horses of the Military Riding Institute in Hanover, in order to enable the development of scientific instruction methods for the cavalry school." [2] The 24 electrically interconnected cameras made motion studies he combined to image series. Other series show human movement studies. [3] In 1886 he developed a device for the projection of his series images, which consists of a disk with a diameter of 1.5 meters and 24 glass plates in the format 9 cm × 13 cm. The photo plates illuminated from behind with a Geissler tube are rotated by a crank drive at a speed of 30 frames per second. In 1887 he presented his "electric speed-watcher" - the electro-tachyscope - in the Ministry of Culture in Berlin. Siemens & Halske began commercial production of the device in Berlin, which was widely used from about 1891.
I'm notoriously skeptic when it comes to this Edison hype. In my opinion it often doesn't hold the proof. (Opinion: The only aspect of his I admit he was better than his competitors, was his marketing and self glorification skills.) As I read the articles about Edison, it is mainly (French born!) Dickson who deserves the merits, but this is also nitpicking, as he had been Edison's employee.Unlike Dickson, the Lumières used 35mm film, simple perforation and transporter.
Some famous inventors include Thomas Edison, Alexander Graham Bell, Nikola Tesla, and Marie Curie.
The greatest invention of all time is subjective, but some commonly cited inventions include the wheel, electricity, and the internet.
The process of inventing something involves identifying a problem or need, conducting research and experimentation, creating a prototype, and testing and refining the invention until it is ready for production.
Inventions have greatly impacted society by improving quality of life, increasing efficiency, and advancing technology and knowledge. They have also created new industries and job opportunities.
Patents protect inventors by granting them exclusive rights to their invention for a certain period of time. This allows them to profit from their idea and prevents others from using or selling it without permission.
