I can't be the only one who felt so goddamn proud of humanity for coordinating tasks that spread across so many generations all in the name of science.
ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BZvsrOciU_Q.html i walk past it most days when i am on campus - i've had lectures in the theatre next to the experiment
What's left is our collection of experiences stored in whatever method we come up with to save our volatile memories from disappearing. It's already clear that some people don't care what they originally looked like with piercings and plastic surgery so maybe they won't mind a robot body. What would be even cooler though is growing an organic body in a lab or with 3D printing , but that just seems too far off.
I don't know if you grasp what i am talking about. You are saying that only our memories is wat makes a person a person. What counts as a self being. If i would teach a machine every thing that is me who i am is that machine me or is it a clone? Does the clone continue as me or does it continue as it's own being? A good example are identical twins they are born out of the exact same DNA strands but they are still both a independent being and not just one person with two bodies.
Well we're getting very speculative here now. The way I understand how digitizing a mind is that what memories you and I have are volatile. Once cut off from a supply of energy, you, your master copy of yourself, is gone. So to move a mind from an organic body to a non-organic one that old body would either be connected to the new body briefly or the old body would simultaneously die as the new one is activated.
I was born about a month after the Chernobyl disaster. It was a bit weird hearing people talking about it last year, saying it was 30 years ago. How did that happen? I could have sworn I was 25 a few days ago
Cody'sLab can you capture lightning in a bottle? when you turn the high voltage generator off but keep the vacuum at a full vacuum, will the electricity stay in there like a new version of a battery like in my visions??
I was so excited to see Lenski's research mentioned! I saw him give a talk a few years ago about all of the different things they have learned from the experiment and it was pretty incredible. Hopefully someone continues it after he retires.
I remember reading about the Lenski experiments in a Dawkins book ("The Greatest Show on Earth", I think), and wondering why it isn't more famous. The citrate adaptation is a clear demonstration of so called "macro-evolution", which some people still claim is impossible. Lenski's work deserves a lot more attention than it's gotten. Good on you, SciShow, for giving it some.
@@AntonioDoukas That's just the name given by the furless apes who study this bacteria. If scientists had discovered two different types of vibrio with different cell digest capabilities, they would be likely to classificate it as different species.
Creationists keep moving the goalposts. Once macroevolution was proven, now they say evolution of species turning into different “kinds” of species hasn’t been proven, even though they can’t define what constitutes a “different kind.” Clint’s Reptiles has a great explanation of how they keep moving the goalposts no matter what anyone shows them.
Love that in your weeds part you showed purslane. It is very, very edible and yummy kind of like spinach. It is also great for livestock, like chickens.
There is definitely some merit to that. You have to consider that every mile traveled is essentially two, if you consider the trip back. The further you get, the more likely the need for intergenerational trips will be. Which brings up a whole bunch of other issues.
angeldude101 Do you think there would be enough volunteers to uproot their lives and leave the planet? I would love to see scishow cover the topic of living in space. (If they haven't already)
Flintstoned they wouldn't last that long it was the length of time that was surprising not really the density of the electricity the bell doesn't use that much
well I mean there are calculated estimates to that as the universes survival (depending on your definition of course) can be looked at as how long untill all matter decays into heat.
Approximately 1 googol years, after that, the universe will achieve thermodynamic equilibrium (“heat death”), and nothing will be able to happen after that. There’s a cool website that has all sorts of countdowns. Including the universe’s heat death neal.fun/progress/
Can't believe this episode is a year old, and I somehow missed it until now. I think this is one of the best ever.I love the idea of long-term studies, because the data is so rich. My mother participated in a ten-year study in which they determined, at the end, that an extremely low-fat diet is bad for your health.
"Every 25 years" I can only imagine the scientist's kids (and so on) make a life milestone out of checking those vials. Twice, maybe three times in life. Here's lookin at you kids!
Yeah it’s cool to see how long the bells keep ringing but it seems worth cracking them open in my opinion. If there is something to be learned about optimizing batteries I think it’s worth the sacrifice of watching something cool. Just make another once you know the trick.
The Oxford bell is powered by Zamboni dry piles. I have an old physics textbook, the 1892 edition of Elementary Lessons on Electricity and Magnetism by S P Thompson. In a chapter discussing types of battery in use it mentions that the Clarendon laboratory bell powered by a dry pile of Zamboni had been running for over forty years.
Well, there are some speculations of why that battery lasted so long. The first one is that it is in a vacuum, meaning that there is less energy lost in friction towards air molecules. The second one is that electromagnetic fields are recharging the battery a little. Since it is a metal bell, the heat it generates will mostly be conserved in itself aswell, which helps electric currents to be more efficient. There are so many possible factors that could be included, there is no telling what yet. As for the files missing, there are actually a lot of experiments and items that we cannot simply recreate due to missing files. Experiments and files tend to be seperate, because if one burns down or gets stolen, you can still make the other again from the surviving one. If the original files were burned down, we can easily recreate them by opening the sealed case.
Predated “the heat it generates will mostly be conserved in itself as well, which helps electric currents to be more efficient” Weird that people spend billions of dollars on cooling electronics
The original pitch drop experiments were devised by Lord Kelvin in Glasgow University (where a demonstration piece he set up is still running) in the 1880's. There is also one still running in Edinburgh as well as Aberystwyth both of which pre-date the Australian experiment.
I'm a physics alumnus of U of Q, and now feel very old that the now 90 year old experiment was a little more than 50 years old when I started there. I was around for the fall of the 6th drop, although of course I didn't see it.
Here‘s another long-running experiment: Cryonics! Already running for several decades in two locations in the US, and more recently also in Switzerland, China, Australia and Russia.
The "Time Pyramid" is a work of art under construction in Germany. It will consist of 120 blocks where each block will be placed in every 10 years. The construction began in 1993, has 3 blocks until now, and will finish in 3183!
I'm part of a decades-long experiment, but it seems it wouldn't make the cut even if you knew about it :P It tries to study what causes Asperger's syndrome. The study involves 10 boys who all have an Asperger's diagnosis and their parents and siblings, and any future offspring of the boys and their siblings. My brother is one of the boys. We were all tested back in the day, too - my parents, me and my other brother - and none of us have Asperger's. I get a new questionnaire from them once in, like, 5 years (about any symptoms or diagnosis or if I have children). I don't know how long it's going to last. At least a few generations, I'd assume. It started somewhere around 1998-2002.
Maximilian Russell, there's a possibility of ancient batteries, but nothing so powerful. The earliest batteries (if they really were batteries and not an accident in food storage) could only produce about half a volt... There were also some antique jars that could shock you on a touch. Those were Liden's Jars (not sure of the spelling)... And they were actually the earliest capacitors. It's fairly easy to look up and even build one of them yourself. I did once for science class out of a gallon-size pickle jar... hilarious! :o)
I Heard That A Plant Seed Was Trapped In Permafrost Since 9500BC, After A Arctic Squirrel Buried It But Forgot Where It Was, The Seed Was 50ft Under The Surface When Scientists Unearthed It, They Planted It And It Grew Into A Narrow-leafed Campion. This Is The Oldest Seed Ever To Grow Into A Plant.
It's funny that you chose a picture of purslane when you were talking about weeds. Purslane is an edible plant that is quite nutritious and makes great salad or light munchings in the garden.
before i continue to watch let me tell you the longest experiment in MY opinion and what i think is. The pitch experiment, you know, the dripping pitch one, the most viscous fluid in the entire world
9:48 Don't worry Hank, even if we all die by then you will be replaced by cyberhank who will have identical memories and will use his ability to communicate ideas straight into a computer to make sure that SciShow never dies.
1) The batteries last along time but they are not producing a lot of power. 2) They already have a pretty good idea how the batteries are made. Modern tech can produce higher energy density batteries than these can.
crazyguywithasword Obviously not... I'm not that ignorance... I was being sarcastic... Seriously, Hank even said, they were video taping it... You don't exactly have to be Einstein to rewatch a recorded video to figure out the drop interval...
These are all pretty neat experiments, and as an Otago student I have to do a little plug - I think it also would have been pretty cool to mention the Dunedin Multidisciplinary Health and Development study which has been running for over 40 years now (and shows no signs of stopping).
Went overboard and tested this by recording it in audacity with my sound card and running it through ReplayGain. The intro and the first 20 seconds of speech are at almost identical in volume (the speech is about 0.1dB louder).
I know of a multi-decade experiment done with glass to prove that glass doesn't flow at room temperature. Three glass rods were suspended horizontally and supported at both ends. Weights were hung from the center of the rods. Over the years, the glass rods did bend. However, it wasn't a permanent deflection (it was elastic strain, not plastic strain). To prove it, the weight was removed from one of the rods. Within 24 hours the unweighted rod returned to being a straight rod. I have a book (no longer in print) on glass science that mentions this story.
In school I also learned that glass is a slow-moving liquid but this is actually an urban legend. Consider that there is plenty of ancient volcanic glass all over the world which has not puddled in the least since it cooled millions of years ago. For more details see www.cmog.org/article/does-glass-flow
I think its amazing scientists rather watch and see how long a battery will last rather than crack it open and potentially discover a source of energy that could change our world.
The battery although amazing has been doing a rather simple task, researchers could crack it open and figure out that our current technology is far superior and there is little to learn from it. The past still has much to teach us but I doubt the battery is any better then the ones we have today.
As a scientist, they are obligated to see the END RESULT of their experiment. It might seem ethically useless, but for measurable data is an important point. Let's just say there were 5 other battery experiments going along with this one, all died out within their set perimeters, and this one is still going on, the scientists in charge will want to see what the eventual outcome of this outlier really is.
There is the Beverly Clock that was made at the University of Otago in 1864 and is still running, without ever being wound up. I am not sure if that is still an active experiment though.
