They have invented plenty- Manned space travel before the US, in war fields- some very advanced submarines such as the siphon-assisted (Russians did not use the term Snorkel) A-9 class used in World War I by Czarist Russia, Color Photography in l906. Closed Circuit TV for use in relaying documents and composite sketches- etc for the Police Agencies. First Multi-engined airplane in l9l3- some very real advances in Camera field- even in modern times.
Russians made key contribution in space explorations (first sputniks, first robotic Lunar rovers (Lunokhods which were in fact also first extraterrestrial robotic rovers) , first space stations etc.).
Nikolay Basov and Alexander Prokhorov shared the 1956 Noberl prize for invention of lasers/masers with American Charles Townes. Vladimir Zvorykin and Vladimir Rosing are considered ones of key inventors of TV. Alferov invented quantum heterostructures whithout which modern electronics is impossible (Nobel prize, 2000). Dolivo-Dobrovolsky invented three-phase systems which is the basic element of modern electrical systems.
Such Russian inventions like arc welding (Nikolay Benardos), the first commercially viable and mass-produced type of synthetic rubber, so called polybutadiene synthetic rubber (Sergei Vasiljevich Lebedev),napsack parachute (Glep Kotelnikov) and light diod (Oleg Losev) are also worth of mentining. In fact many things were invented by several nations concurrently like incandescent lamp and radio and Russians have their inventors who participated in it (Lodygin and Popov correspondingly).
The last important invention is Graphene (Konstantin Novoselov and Andrey Geim - Nobel Prize for 2010). Some inventions were ahead their time - Vladislav Ivanov invented magnetic resonance imaging as early as in 1960s. If you are realy interested what Russians invented see the list of Russian inventors in Wikipedia for example.
The man who invented the toilet--John Harrington--was an English nobleman. The infamous Thomas Crapper didn't invent the toilet, but he DID invent, among other plumbing products, the drain trap--a more important product than the toilet, as it made plumbing safe to have in your home. The trap keeps poisonous sewer gas from entering your house.
Technology is the aftermath of the being of science. Without the science to learn about anything, how can there be ways to invent new technology.
I charge $226 to remove and reset a toilet in the Los Angeles area. This is a standard price, but there are always exceptions for vintage toilets and other non common situations.ANS 2 - Anything over 1 hour labor to remove and reset a toilet is over charging. I do many and make a reasonable profit charging less than $100
Yes if the vent pipe is 4" and vertical by code and there is nothing connected between your toilet tee and where you would connect your new toilet tee. If not worried about codes then yes you can connect to a 3" vent line if no other vent lines are connected down stream. If you have a vent pipe that is less then 3" and or you have other vents connected between your old toilet tee and your new toilet tee then NO you can not connect a new tee for your toilet.
either the vert is plugged and there is no air getting through or there is no vent at all

You throw it in the dirtbin/dustbin/waste bin. Whatever you call it depending where you live. Do not put anything down your toilet other than toilet paper, i am repeating myself now, DO NOT put anything down the toilet other than toilet paper.
