Hearted Youtube comments on Dr Ben Miles (@DrBenMiles) channel.

  1. This is a fantastic video about ion propulsion! I would like to mention about the Ion Propelled Vehicles shown online and on my channel. The series of crafts have a greater than one to one thrust ratio, with onboard power... No other ion thrusters that I am aware of are within an order of magnitude of lifting their power supplies vertically, normally ion thrusters are many orders of magnitude away from a 1 to 1 TWR. There are some videos of the crafts carrying onboard propellant tanks as well. They will have a tremendous ISP in space since they operate at very high voltages. It is surprising the project currently gets so little funding.

  9. But surely the science of turning genes off and on is useless without understanding what all the genes do when they're turned on, and only a very tiny amount of the gene code has been cracked? Why is that when we have bioinformatic software and very powerful computer power these days?

  10. Hi Ben - There are one or two completely separate points I would like to raise. I may have to split into separate comments to avoid a ridiculously long comment. Most important thing first - The SAFETY implications of Veritasium giving people "a little knowledge" (was it Edison who said "A little knowledge is a dangerous thing"?) - I was VERY alarmed at some of the comments on his video, people seriously talking about whether it would be considered "stealing electricity" from HIGH VOLTAGE TRANSMISSION LINES, if they weren't actually making a physical connection but just relying on induction to tap energy from the lines in their community. (I think the user name was ZEET) The DANGER of even getting within a few FEET of HV lines makes me shudder. High voltage can jump several feet - It doesn't give people any warning - it just fries people in an instant before they get "close" - The air ionizes and then there is a massive three phase flashover - They certainly wouldn't be able to touch the lines anyway for that reason. Even at 230 / 400 volts (industrial three phase - so called "low" voltage) one small mistake causes the air to be ionized and again, a three phase flashover. (An electricity supply engineer I knew, made a small mistake changing a three phase meter and needed 6 months off work - became a born again Christian - said it was like a hand grenade going off. Unqualified people can be VERY casual about electricity - operating industrial switches with a pair of pliers, so they can keep the cover open to make fuse changing easier - DAFT things like that - We have to do everything we can to stop giving people HALF BAKED information about how electricity distribution works - Everybody thinks they are an electrician for some reason but most are blissfully ignorant of the dangers they cause to themselves and others. I just think we have to be very careful before giving people the false idea they can put some cable "near" a transmission line of ANY voltage and "tap off" free electricity - desperately poor people will do desperately stupid things. It wouldn't work anyhow because Veritasium's claim is very misleading and gives desperate people false hope that there are ways to tap off free electricity in poor communities where this is rife anyway. People get killed even trying to steal live cable in Britain. ANYWAY - that was my main concern first. On second thoughts, I would like to do some actual experimentation work to illustrate one of my objections to the sweeping claim made by Veritasium - I don't mind things being "unintuitive" - who am I to argue with nature - but if I can show nature doing something that is supposed to be impossible, if we are to take his word quite literally, then it MIGHT be a good reason to re-examine his claims. I think I should be able to construct my experiment in a day or so - that would be better than me making thought experiments, which seem to be all the rage. OK so just one more thing - Should be more up your street... Optics being your field of expertise, you may be interested to know of another quite famous You Tube scientist making a claim I feel sure you would dispute - Just like you, it's been "bugging me" ever since hearing Professor Moriarty of Sixty Symbols fame, (Nottingham University) inform us that if the E field of electromagnetic radiation is oscillating, say, vertically (for example - as in a simple upright radio antenna) then it can "slip through" the narrow gaps between the vertical bars of a suitable polarizing filter (say, a WIRE GRID polarising filter typically used with 10GHz microwaves for teaching purposes) BUT WOULD BE BLOCKED (he say's) with the filter bars turned HORIZONTAL relative to the VERTICAL E field vector. He even has a special "snake like" plastic rule, to physically demonstrate how it slips through the gaps in one orientation but cannot physically pass through in the other. That video (about 3D glasses) has been up for nine years and I'm quite sure no correction has ever been made ... Last time I checked a year ago, only TWO comments out of about 1000 at the time, pointed out that this is not how polarising filters work - and that the orientation he describes PASSING light / radio etc is in fact the orientation which BLOCKS - because the E field - or the magnetic field at 90 degrees to it obviously, is then effectively able to "induce" current into the bars. (my layman way of thinking about it) Forgive my LAYMAN talk - it's just easier for me to remember how it all works if I pretend there is no near field/far field distinction - then for me it just looks like two relatively long conductors parallel to one another (rather like Veritasium's very long wires just 1M apart) and straightforward EM induction. No, I have no qualifications in this so I lack confidence expressing my doubts in an actual Professor, but i have checked many many times, invested in ex school equipment etc so I can learn for myself - and so I am quite certain Prof. Moriarty is wrong. What say you? I've just checked again - The Sixty Symbols video is now 9 years old and is called HOW 3D GLASSES WORK, 650,000 views, about 1,300 comments now - I don't fancy trawling through every single one again - The first 50 or so recent comments are just the usual fawning over how wonderful this explanation is - which bugs me even more of course. I still cannot see any amendment or correction. The relevant bit starts at 4 minutes in. Sorry for the lengthy message. Oh and yes - it felt wrong for Veritasium to say we've been taught "lies" - I will try to get my experiment together ASAP - nothing posh - just to illustrate a possible flaw in his sweeping statement. If I end up proving him correct I'll be gobsmacked.

  12. Your videos really help me get a less bias understanding of the experience, thank you for sharing your opinions on the subject. It sounds like there really is something you get from a PhD that you just can't get at home. I got cynical when you mentioned they spent a few million on an isolation chamber that functions as well as the countryside, but your story of being grilled by your teammates to fill in your intellectual weaknesses was really cool, there seems to be something to the in personal social component that just doesn't exist as much digitally. Your part on distractions was really inspiring. Do you think the deadline to submit your thesis and/or paper was itself a distraction, or a motivating factor that's responsible for the researching being done in the first place? A little of both? Would you have done more without the deadline, or less? Also when is it too late to start a Masters/PhD? I mean "never" is a nice answer but like practically, is it 23? 25? 30? Did you notice any significant disadvantages for people graduating around the age of 30? I hope your business is going well!

  13. I completed my PhD in science at 51. The process took 10 years. I have a masters by dissertation in Elec Eng as well. You really have enjoy what you do to last the distance. In a conventional sense they are a means for signalling. That means I have some acronyms that signal I have gone through a certain process, I have proven that I can logically work through a problem and am able to construct processes to seek solutions. How old is too old?. Only you can answer that. I can say that it's better to start earlier, as life does get in the way, from a finacial point of view (I'm 64) on the one hand it becomes a diminishing returns scenario, on the other hand its helped me tremendously in securing jobs. Couple the acronyms with the weight of many years of experience and it is hard to beat compared to an inexperienced player. What can work against you is that there is the expectation that you need to be paid commensurate with the lack of supply of people with your background. Thatmeans that normally only large companies and funding bodies are able to employ you. If you really like a job with a smaller commercial firm, be prepared to sacrifice salary for stimulus and challenge. Don't necessarily base all your decision criteria on salary, it is extremely important to consider the calibre and vision of the new people you are considering working with. Would I do it all over again? You bet, just for the intellectual stimulus. Hope this helps. Good luck in your choice.

  22. 1:38 metric units > imperial units, and the reason I have for it is personal: I grew up learning only german because I was born in germany, I had to learn english in school and after school by myself when I was 12, it only was ok-ish when I was around 18 years old, it still isn't perfect now that I am 27 years old. I put so much work and effort into learning english just so I don't fall behind on general knowledge etc. There are like 2 billion people who speak english, but only 100million that speak german, so I have 20 times more content in english. Now the thing is: most people switch to english, but they don't get paid for it, we just have to to open ourselves more doors for success. almost every nation uses metric units, so while we learn 10,000 and more words to be able to speak english, americans can at least learn like 10 extra units... it's just so unfair, and this is the reason I am against imperial units

  27. I liked the essence of the video which I think was what and how you can do the various things after a PhD other than going into academia and what a doctorate will transform you into even if you don't like it. It was informative and I got to know more things about the process of getting a PhD which I absolutely needed. Thanks a lot Ben!🙏❤️

  29. In the laboratory's quiet hum, Dr. Ben Miles, with curiosity drum. A quest embarked on the evolution trail, A scientific dance, where wonders unveil. In petri dishes, a microcosmic scene, Evolution's stage, where life convenes. Did scientists prove, in the lab's embrace, The dance of life, in its genetic grace? Ben Miles, a guide in the scientific sea, Where microbes evolve, in a mystery. A testament to life's adaptive power, In the lab's confines, an evolving hour. Microscopic realms, where changes brew, Evolution's dance, in a petri dish view. Life's journey, in genetic codes inscribed, Dr. Ben Miles, where science is imbibed. A tale of adaptation, in the laboratory's den, Did evolution unfold, in a microbial blend? In the test tubes' ballet, a genetic rhyme, Dr. Ben Miles, decoding evolution's time. In the silent hum of the lab's allure, A discovery profound, where knowledge matures. Did scientists prove, in the petri dish's sweep, Evolution's dance, in the microbial leap? So, in the scientific journey, where questions unfurl, Dr. Ben Miles, in the evolutionary swirl. A testament to life's ever-changing plan, In the laboratory's realm, where science began.

  30. Automation will follow a threefold rollout, we're in between the first and second. 1. Businesses use robots 2. People use robots 3. People have robots in their pockets. It's the same trend as Computers. A motorized, humanoid robot with a traditional kinematics system akin to a 6 axis arm, are probably going to fit the 80s-00s mold of personal computation, personal automation, and Tesla has quite impressive battery and motor technology that can and will be used in this robot. Largest hurdle, for them at least, will be creating an interface platform between the hardware and software, which would allow independent software engineers to create and improve existing "commands/programs", potentially even profit off their contributions. Constructing a humanoid robot is simple, having it be smart enough to perform useful labour efficiently, is the problem they must solve. This however is just a fad, shapeshifting robots, aka mesh morphing robots, will take over after this, which will allow the consumer to fit a humanoid robot in their pocket. I personally hoped that mesh morphing robots would reach the consumer space before their traditional counterparts, but with the progress being made by boston dynamics and musk it doesn't look likely. I expect he'll release some barley useful product 2.5x past his initial release date, to actually compete in this field would take initial capital investments comparable to that of SpaceX, I'm not so sure he has anything other than good motors, batteries and money to throw at the problem, and I don't think that's enough to solve the second stage of automation, this far into the race. He'd have to acquire BD and/or a few other companies to really stand a chance.

  35. from an auto-didactic opensource hack as myself, it is a challenge to speak as eloquently as you after watching this. And I dare not presume, that it would be solely my community and myself who would benefit from your mentorship and focused attention. Regardless, there are countless things from treatments to economics, business incubation, and quantumn that I would find gainful to learn via your continued uploads. Please, continue. I appreciate the time you take to document, edit and disseminate. Wave function collapsed. :)

  36. The thing I don't understand is distance and position seem to be very important but entanglement just ignores these. It doesn't matter how far away, they're somehow linked and if they both collapse when one is measured surely there must be information passed between them somehow? Also, is it possible to know when the measurement has occurred? For example, if I have an entangled particle and you do too, is there any way for you to know when I measured mine (thus changing yours)?

  37. Thank you very much for the sharing and digestible information, Dr. Ben Miles. Really appreciate your perception of the impact on deep tech investment realm from Theranos’ case. Can’t agree more how dangerous it would be for laymen investors (and even investors) of no/ low specific science background to try investing (or should I say speculating) in the realm of deep tech start-ups.

  41. Thank you for making this video, you've provided some really interesting insight. Sometimes I forget a main goal of patents is to assure the publicization of information. I personally don't publish some of my research out of fear of being beaten to the market. I think patents would work a lot better if they were more affordable for average people, filing a patent, hiring a patent lawyer and defending your patent is unaffordable for most normal people. Which means, if seed capital is dependant on the applicant holding a patent, only a small portion of the population can afford the privilege to even apply for assistance to participate in the free market. I agree with you that the best solution is keeping patents, and sanctioning and/or subsidizing the drug's MSRP. However I also think drug companies should also be forced to license their patents to other manufacturers if they're unable to meet the demand.

  48. I found a nice scifi short story about an intergalactic jellyfish that produced both the energy it needed and the materials it cannot find through fusion and fission inside its stomach, was neat can't find it anymore :/ Nice to imagine/pretend nature already solved the problem though, helps make the problem appear more solvable. Great video, like always, finally got your skillshare course, looking forward to it! Side note, whilst centralized power plants will always be most efficient for cities and such, I've been patiently waiting for some sort of traditional nuclear energy generation to trickle down to the consumer space. If the Navy had nuclear reactors to power their ships for decades, it must only be a matter of time before we have em in our basements right? I just purchased land off the grid, and I'm really desperate for a proper power plant, centralization of power generation and distribution works in areas with high population density, less so for rural ppls. That might be a neat video, explore the current attempts and theory behind consumer nuclear energy generation.
