Before my eyes, there was no fault or mistake. Those who had the opportunity to be your students are VERY lucky. And that speech (demonstrations included)... Priceless! 🥰👏🏼
Truely in sync with the Mr. Yeany's character which I kwnow from this RUclips channel: entertaining, funny and most importantly - heartwarming. Thank you for sharing that speech!
I never was in this class but i know how awesome it would've been to be part of this. Teachers like you are what makes the world and science about the world interesting. I would've never missed a class if my teachers would've been able to do the same for me. Your YT-channel has compensated though. I now know that we can use every day objects and little experiments to make this world magic and turn it to a nice and entertaining place which brings joy and more knowledge to us. I wish we'd recognise the value of people like you and would vote them into politics instead of agenda-driven ... . I am sure you'd used the influence to great extend and invest time and effort in education to make us and thus our society an exciting and awesome place and people to be around. We'd debate experiments and their outcomes instead of fighting over appropriate clothing, issues of identity or other boring stuff. We'd see exploding balloons at every corner, duck away in the sweets ailes of the super market as flying mentos would come our way and play bowling with catapults. Doughnuts wouldn't be lousy doughballs with a hole but potential projectiles for our new air cannon. And whenever we'd feel void by exhaustion of so many incredible experiments we'd remind ourselves that creating a vacuum surrounded by atmosphere requires a lot of energy and reduces the resistance for the next accelaration. Sir, you can't imagine how thankful i am for the excitement you have brought to my life and many others. You have done an incredible job at helping me imagine an exciting and awesome world. I don't think there's any better gift you could have given as a teacher and i wish the same could be the case for our leaders in the future. I don't want to ask as certainly what twain said wouldn't be applicable to such a task. But if i ever had the opportunity i would vote for Bruce Yeany for president. I mean, just imagine the inauguration speech ...
I thank you for all the kind thoughts here, but I think I will stick to science. However, with the resources and money available to go large scale, planning out the inauguration speech would be a dream come true.
To try to do public speaking *and* carry out a physics demonstration, each of which has low probability of success, is courage in the face of experience. Well done! Now join the rest of us old educators in enjoying _faux_ retirement.
Hey Bruce, you are one of a true “learning by doing” teachers out there in the world. Great experiments and I hope you are doing well after that trip over on the bush :(. Please take care and my best wishes. I hope to meet you one day 😊🙏
The absent-minded professor comes to mind. However, I can easily envision your classes being fun & informative and looked forward to by incoming students.
Respect for you and your passion for teaching respected sir, wish you luck for your next chapter in life. Perhaps, what brought about this decision of retiring? You look like u could continue for a good 5-6 years in the least.
Sometimes spontaneity beats planning, and what is going to happen is going to happen, just do your best, make your attempt and don't stop no matter what, According to Newton's third law: "For every action, there is an equal and opposite reaction" now if we can only know how much energy was produced from the reaction between the coca cola and mentos, I think we can calculate the damage happened to Mr. Bruce, otherwise we can prove that Newton was wrong 😎 Thank God for your safety
This example isn't a violation of N's 3rd law. The bottle experiences a recoil downward, and would temporarily weigh more than the weight of its mass at rest, during the impulse from launching the fountain. You can try this experiment with a scale below the bottle that gives a digital feed to a computer, and you will see a spike from when it launches the fountain of soda. If the bottle were free to move from the recoil, it would propel itself like a rocket. There is a way that Newton's third law is proven "wrong", although it still has a kernel of truth. When two charges approach each other on perpendicular paths, they experience magnetic forces that are equal, but not opposite, which may seem to be a violation of N's 3rd law. However, if you consider N's 3rd law to be conservation of momentum more generally, it is still valid. The deal is, there is a third agent involved, the magnetic field, that can store momentum as well, in order to enable the two charges experience forces that are perpendicular to each other, instead of equal and opposite.
@@YeanyScience I really appreciate your reply Mr. Bruce, and I know how it feels like to leave your students, but at least you made a good impressions over all these years that your students might find hard to forget, Wish you a good healthy life and looking forward for more amazing videos,👍🚀
You tried to get away, but they pulled you back in. This time are you retired or you'll be back to school come fall? The next science teacher has it easy, they just need to watch your videos.
@@YeanyScience 6:50 starting in the fall or because of the fall 🤔😁, No one can defeat you in science even when you fall, dear Mr. Bruce. Thank you so much for sharing these moments of your life with your sincere virtual students 👏👍
Mr. Maguire said he had just one word for Ben the graduate. "Plastics". You might have said this word to your graduates. "Hydrogen". One of them might be the next Elon Musk of hydrogen cars. Elon Musk has scoffed at the idea of the hydrogen cars but Tesla just came out with a hydrogen car. The per capita consumption of gasoline in the US is about 1 gallon a day. With gasoline prices near $5.00/gallon and rising, it would be very good time for someone to find an economical way to make hydrogen from solar and wind for a hydrogen powered car. A frequent objection to solar and wind is that they are not available all the time. And storing the electricity in batteries is expensive. It costs about $1000/kwh for a Tesla Wall battery system. Suppose there was a better way to store the energy. Most of the solar energy is wasted by solar panels and just blows around the neighborhood as heat. But suppose the energy was collected and stored as heat. A ton of gravel will store about one Kwh of energy (3.6 MJ) per 5°C increase. So a one ton pile of gravel raised 500!°C would store 100 Kwh. A ton of gravel costs about $50 vs $100,000 for the same sized Tesla battery. Heat can be stored in gravel for weeks or months if it is well insulated. But how can the heat be collected in the first place and then turned into hydrogen? Aluminum is a very good absorber of heat. There are black surfaces that will convert near 100% of the incident solar radiation into heat. Some large scale concentrated solar facilities pump molten salts through pipes to collect the heat and boil water to make steam. Others focus the light on a chamber of compressed air to drive a gas turbine. Suppose it did not cost zillions of dollars to make a rooftop system with a compressed air system. A typical roof on the sunny side of a house receives about 500 kwh of solar energy on a sunny day.. If a heat engine could extract the energy at 30% efficiency and electrolysis is about 50% efficient in converting electricity to hydrogen, that is about 270 million Joules or about 2 kilograms of hydrogen. 2 kilograms of hydrogen is the equivalent of about 2.25 gallons of gas in Joules. But a hydrogen fuel cell is two or three times as efficient as an internal combustion engine in miles of range. So the equivalent daily production of gasoline from an average rooftop on a Sunny day would be about six gallons. The waste heat from thevsystem could be used to generate the electricity for the house and heat the house and the hot water. But the system must cost zillions of dollars. If a small gas turbine was mass produced, why should it cost anymore than a lawnmower engine? The rooftop collection system made of sheet metal and and plastic or glass might cost a lot less than solar panels. There is a video on this channel that shows a cylinder spinning around as it is heated by the sun. Suppose a simple gas turbine could be made out of a plastic jar. There is a steam engine called the Hero engine that uses two nozzles releasing high pressure steam to drive a container of boiling water around in a circle. Suppose two small nozzles were released high pressure air from the plastic jar heated by tge sun. But the air would expand and then stop expanding once the pressure was relieved. Suppose two holes were put in the lid with little funnels to act as compressors. The compressors would resupply cold air to the jar to be heated and expanded. If the holes in the lid were sufficiently closer to the axle than the nozzles on the edge of tge jar, it seems that the torque from the nozzles might be great enough to drive the whole device around in a circle at an accelerating rate that might reach tremendous rpms. A 50°C increase in air temperature that might not melt the plastic ja would increase the pressure in the jar from room temperature by about 20% or 3 PSI. A 500°C increase in a metal chamber would increase the pressure by about 25 PSI. That is enough pressure to spin a soda can around at zillions of rpms. ruclips.net/video/eaCHH5D74Fs/видео.html
@@YeanyScience Great commencement speech. Great movie. College commencement speakers have been making much mention of climate in recent times. I didn't get invited to do the commencement speech at Harvard or MIT this year. The graduates at MIT have been urged by the last few commencement speakers to save us from a carbon dioxide climate crisis with which I disagree. But according to ice core records, there will almost certainly be a climate crisis at some time in the distant ir not too distant future caused by cooling. When I was a student back in the 1970'ss, the concern was about the two or three degrees of cooling since the 1940's and concerns that the next ice age was rapidly approaching. According to the ice core records, the Earth is at or near the end of the ten thousand year warm period and the rate of cooling will continue to increase. The current crisis is a political crisis caused by a handful of corrupt government climate scientists who changed the long term cooling trend into a warming trend when it stopped warming up in the late 1990's. On top of the inflated price of gas, governments are expecting the citizens to come up with increasing amounts of cash to combat an imaginary climate crisis. But it would be good for a long list of reasons to change to a renewable energy powered world. If a $50 pile of gravel can store as much energy as a $100,000 Tesla Power Wall and make gasoline for ten cents a gallon, it would be a big relief. And the storage of large amounts of heat would be very useful for a cooling climate. A one stage gas turbine that could extract the heat and electricity is probably within the capacity of diy homeowners. Can the gravel be heated and cooled at a high enough rate to keep up with the supply and demand? A ton of iron is more conductive and costs a small fraction of a Tesla battery. But if the gravel was small enough, it might have the increased surface area sufficient to store and extract the heat at a sufficient rate. In northern regions they store heat in gravel for months at a time that is stored in the summer then extracted in the winter. The internal combustion engine can be modified without too much trouble to run on hydrogen.. Is a high pressure hydrogen tank more dangerous than a gasoline tank or EV battery at 500 Volts? Hydrogen is non toxic and dissipates much more quickly than gasoline. A collision bad enough to rupture the tank might be more dangerous than the effects of the ruptured tank. It would be good news amidst all of the bad news for someone to design a rooftop system that makes gasoline for ten cents a gallon.
It is the unexpected events that will make this speech memorable...
What a speech! Mr.Yeany you were the best science teacher I have ever had in my years of school
Congrats on reaching 300k subscribers Mr.Yeany
Before my eyes, there was no fault or mistake. Those who had the opportunity to be your students are VERY lucky. And that speech (demonstrations included)... Priceless! 🥰👏🏼
As a starting teacher i admire your action so much! I can only imagine how much your students must have learned about science and life!
Truely in sync with the Mr. Yeany's character which I kwnow from this RUclips channel: entertaining, funny and most importantly - heartwarming. Thank you for sharing that speech!
Small class of students. In my graduating class of 1977 we had a total of 896 students. Loved the graduating class speech and the science demo's.
We love all lessons you demonstrated and afforded Sir!
Sir has made a bang literally....with his presentation (-from Bangalore)
How fortunate they were to have you as a teacher.
Always good to have a speech with some bang in it. 👍
Epic fails, Bruce, for a graduation day they will never forget.
Most memorable graduation speech ever!
Great speech Bruce. Very funny and entertaining as usual. It's been great seeing you at the school again. On a serious note, I'm glad you're ok. 👍

I am sure you'd used the influence to great extend and invest time and effort in education to make us and thus our society an exciting and awesome place and people to be around. We'd debate experiments and their outcomes instead of fighting over appropriate clothing, issues of identity or other boring stuff. We'd see exploding balloons at every corner, duck away in the sweets ailes of the super market as flying mentos would come our way and play bowling with catapults. Doughnuts wouldn't be lousy doughballs with a hole but potential projectiles for our new air cannon. And whenever we'd feel void by exhaustion of so many incredible experiments we'd remind ourselves that creating a vacuum surrounded by atmosphere requires a lot of energy and reduces the resistance for the next accelaration.

So the year after I graduate they get this? Great
I've been attending graduations, they asked me
I wonder if those energy papers ever got graded
Are you okay Bruce yeany cause there was a lot of epic fails in this video but congrats tho 41 years that's amazing man
I'm fine, only embarrassed a bit
