7 Danish Inventions You Should Know About

[@papaquonis]

A few other notable Danish scientific discoveries worth mentioning: Ole Rømer was the first to measure the speed of light in 1676. Hans Christian Ørsted discovered electromagnetism (fundamental for electricity and modern technology) in 1820.

[@hiufuxthevideographer9877]

Danes love exploring and technology :)

[@erikthomsen4007]

@@hiufuxthevideographer9877 Ole Rømer didn't exactly _measure_ the speed of light. He mainly discovered that light has a _finite_ speed, which he called "lysets tøven" (the hesitation of light). At the time, it was generally believed that light travelled at an infinite speed. When he discovered that this wasn't the case, he met significant resistance from his peers, but eventually it turned out to be true. However, he did estimate how much time light would take to travel the diameter of Earth, which can lead to an estimate of the speed of light. While the estimate isn't very accurate with modern eyes, it is still remarkable, given that he did it in the 17th century. Ørsted is one of my everlasting heroes. It is amazing how much stuff he did for science, the discovery of electromagnetism arguably being the most important one. Much of what he did is explained in Energimuseet (the Energy Museum) in Tange. I highly recommend a visit.

​@@hiufuxthevideographer9877 Well, as a former world superpower - the last 200 years we have lost everything. That's why we had to start inventing stuff because we have no natural resources. Now we have a bit of oil, but just 50 years ago we only had fish, then when artificial fertilizer was invented, then we got farming. But for a few hundred years Denmark was a shithole place to live perhaps amongst the worst in Europe. Until we started educating the people.

Great video! Niels Bohr actually had a pipeline of beer from Carlsberg into his private home, as a show of honour to the gentleman. He also later worked on the Manhattan Project, and we all know what that ended up with. He was also the reason why we never got nuclear power in Denmark, as he was prohibited to talk about nuclear power by the US goverment. The famous speech given by President John F. Kennedy, announcing his intention to go to the Moon was written by a Danish immigrant Johannes Jensen. Lastly; for a long time a Dane was actually said to have invented the hamburger, another Danish immigrant who worked as a blacksmith in the US. At the turn of the 19th century, the Danish immigrant Louis Lassen sold steak sandwiches out of his lunch wagon in New Haven, Connecticut. From a place called Louis Lunch which still exists today. The burgers are now prepared by Louis’ great grandson Jeff Lassen, who currently runs the restaurant. The “no ketchup”-sign is visible hanging in the restaurant and an informative caption pops up to read: “Yale students who try to sneak in ketchup are asked to leave”. It is however later discovered, that it was a yank who made the first hamburger. Buut, still a good story! :)

I'm sorry to have to put on my Danish physics hat for a moment and offer a slight correction to your breakdown of Niels Bohr's contribution to the understanding of atoms. It was not Niels Bohr who came up with the idea that the atom consisted of a dense nucleus with orbiting electrons. The idea had been around since the late 1800s but it confirmed with certainty in the years 1909 to 1911 due to the work of E. Rutherford and the Geiger-Marsden experiment. But Rutherfords atomic model had a big problem in the understanding of classical physics: According to classical theory a charge in an orbiting motion should radiate electromagnetic radiation continously, and in so doing loose it's kinetic energy and spiral into the nucleus. Yet atoms were clearly stable over long periods of time so this was not what happened. Also, when performing spectral analysis of the emitted radiation, it showed bands of isolated frequencies, not a continous spectum as predicted by classical theory. Bohr key insight during 1912 and 1913, for which he won the Nobel Price, was to make a rather far-fetched assumption (partly inspired by the work of Max Planck), that the orbiting electrons could only exist in certain isolated orbits, or to put it exactly, that the orbiting electrons had their angular momentum *quantized*, and that the single frequency emissions arose from electrons transitioning between these discrete orbits. Further he postulated that there existed a minimum orbit, a ground state if you will, where an electron would not be able to have it's energy decreased further. He crunched the numbers for a Hydrogen atom and the result matched the observed spectrum of hydrogen exactly. I mean, really exactly. This discovery that particles on the atomic scale are confined to discrete energy states, rather than a continuum of states, marked the beginning of the most important branch of physics of all time, and it came to be named after the peculiar quantized angular momenta: Quantum Mechanics.

Nobel prize winner, Jens Christian Skou might be worth a mention for his discovery of the Ion transporter, known as the Sodium-potassium pump ( danish: natrium-kalium pumpen), while slightly difficult to explain in layman's terms - It is found in all human cells and is pivotal to the body's function, maintaining an optimal ion balance in the cells - this transporter uses about 25 % of all energy in the body measured in ATP - the molecular unit of currency

[@peashooter950]

That was in fact a huge contribution to science, so well worth mentioning.

[@meibing4912]

Lots of things could be added. More recent inventions are two of the top ten IT inventions ever: C++ and BlueTooth programming languages (BlueTooth as in King Harald the Blue Tooth with its Viking logo).

[@meibing4912]

Apparently not Blue Tooth anyway…

[@RobeTrotting]

Yeah, Blue Tooth was a Dutchie working in Sweden. It’s a funny common misconception though.

[@steveharris7189]

The name Lego is from the first 2 letters of the 2 words (le)(go) leg godt which means play well or good in Danish

[@Purplefishish]

Fun fact: LEGO is short for Leg Godt - Play Well

[@bloodywerewolf2533]

Another inventon that Denmark made was Unity and Skype if I don't remember too incorrectly.

Actually, tape recording is far from dead. There are still records, that are being recorded on tape, the so-called AAC, AAA or ACC methods. The first letter stands for the recording itself (analog), the second for mixing (analog or digital), and the last for the medium type (LP or tape is analog, digital media such as CD or file is C). In the computer world, analog tapes are still widely used, to store wast amount of data. For instance, CERN stores all their data on tapes. This is a slow process, but the only way to store their measurements. One measurement of data from the Large Hadron Collier can run into many terabytes of data. It would be incredibly expensive, to store all these data on harddrives. Here's an explanation from a website, regarding data storage at CERN: "Data Storage The LHC experiments produce over 25 petabytes of data per year. These are transferred to the data centre where initial data reconstruction and archival is performed. 100 petabytes are kept in mass-storage systems - the equivalent of 700 years of full HD-quality movies. Magnetic tapes are used as the main long-term storage medium. To access the files, special robotic arms find the right tapes and load them into the tape drives. More than 480 million experiment files are stored in the data centre."

The torture devices for Women and girls called curlers, the plastic round thingies girls put into their hair to get curls after washing. As for Beer, heres some fun fact. 1) It has been found as offering in graves in Egypt from 2800 BCE. 2) The worlfd oldest written recipe is Sumerian for beer from around 1400 BCE, it has been tested, annd should be fairly good. 3) The worlds oldest love song/poetry is to either A) A small house God or B) A very lovely Lady that was very good at making Beer and make you feel good, it as like number two Also from Sumer and somewhat younger than the recioe

Carmen Curlers was a global success story.

[@jacobehlers2387]

i actually made a school projekt about danish innovation and im so glad that you had at least two of the things i had in my presentation btw bubble wrap is also a danish invention but when it was time to mase produce the produkt it only lated a year and then the factory closed down the production andsaid to (cant remember the inventers name) that there was no future in bubble wrap but shortly after the sister factory in england coppied the bubble wrap

[@liskofod8711]

I like Your facts. GOD PÅSKE 🐤🐣🐤🌹🐣🐤

[@RobeTrotting]

Thank you, god påske to you too 😃

[@lineillummundus6401]

maybe bluetooth could be mentioned;) it is baced on a old danish king called: "Harald blåtand"

[@RobeTrotting]

True, but only the name is Danish, the inventor was actually Dutch and his research was done in Sweden.

[@Johanhoimarkjohnsen]

Its actually not called a loudspeaker its called a soundboks

[@koiyujo1543]

as an american I'm aware Lego Came from denmark because I watched their documatary

[@VilladsAlex]

Actually Ole Kirk did not invent the lego bricks, he just saw the plastic pressing machine while being at a showcase. It was him *and* his son who made the first kind, then after his fathers death he made the bricks that connected that we all know and love today.

[@peashooter950]

AKA injection molding.

[@bentebunting9568]

I have some of the first LEGO ever produced and it has passed on to my sons. By the way, LEGO isn't just for boys, the girls of my generation in Denmark cherished it just as much even if it was to build furniture for our dollhouses or for our new Barbie dolls

Do u live in Copenhagen? I live in Denmark 🇩🇰 Aarhus Pls Answer me then u are the best

[@peashooter950]

I also do not Consider Copenhagen as Denmark, in my perspective Jutland + the former holdings down into Germany is Denmark, i have no idea what the hell they got going on over there, but as the last 50 years at least have documented it is nothing good.

[@bentebunting9568]

Not only is LEGO a put together word of 2 Danish words put it also means I put together in Latin.

[@lijojake]

What about Google Maps and pioneers in Diabetic medicine Aren't they also credited to Denmark?

[@RobeTrotting]

Two of the four inventors of google maps were Danish and working for an Aussie company. Not sure which contributor to diabetes medicine - but there are plenty of other things that could have been included in this video of course.

[@esbenjensen3968]

bluetooth is also invented in denmark. nammed afer a big king called harald blåtand. bluetooth means blåtand in danich.

[@broendbykim]

No it isn't - just named after him - It was a Dutch, Jaap Haartsen, working for Swedish company, Ericsson.

I gues you have a Danfoss thermostat on each of the radiators in your home? So look that up!

Bluetooth is also Danish

[@poulsenracing5633]

i actually didnt know some of these and im danish

[@traver1965]

Actually the Dane Louis Lassen invented the burger. I think that should put him on the second spot just after LEGO

[@RobeTrotting]

He was a Danish immigrant in America. We may do a follow up video though and/or do a video on Danish Americans, so he has a good story to fit in a future video 😀

[@meibing4912]

@@RobeTrotting if you do - remember to include the Dane behind the Mt. Rushmore monument.
