I had the felicity to read the extensive collection of online articles you published almost twenty years ago. Thanks very much for your generosity! I have a PhD and would never advise any youngster not to pursue a formal education, but as someone with a range of interests outside my field and a frequent autodidact, I stand by the value of informal study and practical knowledge. In fact, I'd trust a brilliant self-taught technician more than an indifferent formally trained one! I also remember that engineers and craftsmen until a few generations ago went through apprenticeships rather than formal education, and were perhaps more resourceful than current professionals for it. The critical issue today is that STEM applications require ever more advanced mathematics, which are not easy to learn without going through university.
Admittedly I still haven’t googled you. But this whole time I thought you were an engineer! What you say in your videos makes sense and I learn from you every time I watch. Planning on buying one of your books one of these days
I’ve got his earlier book and lots of other suspension books as well …he does his homework and most importantly explains things in a easy to understand manner
Julian is right. I've been a practising Mechanical Engineer for 13 years, but that doesn't mean I know the first thing about this topic. Engineering is very broad and the qualification itself is a foundation of theoretical knowledge, but to have expertise in automotive design and suspension set up specifically, requires years of working in this specialised industry, with hands on practical experience DOING it and learning from other experts in the process. Well done on your achievement with your book Julian
I wish you’d do audiobook recordings of your books. Not as a substitute for the printed book (actually, I think the best would be to include it with the physical book via a download key, or as an add on option), but for those of us who benefit from hearing while we read, or hearing it more than once after first reading. For me, that’s a big tool that elevates from “I understand the broad strokes” to “I am confident that I understand all, or nearly all, nuance and detail in this material.” Besides, you’ve developed a great presentation voice doing these videos, so the skill set is already there.
I know you know what you are talking about as I have done a lot of research myself and before discovering your channel and found that a lot of things you have done and say lined up with a lot of qualified persons, some that are involved in F1 development. So screw those that doubt what you say or do as you do not need a qualification if you have real world experience with experimenting with various types of cars... I now go to you first before searching elsewhere for any answers I need on anything I am interested in doing to my car.
I own a successful business for over 25 years and didn't even finish college. The college degree holders work for me. So don't worry too much about college degrees. I am ordering Julian's 2 books soon. Cheers.
When I first started building my track car I followed the advice he gives and it made things so much better it should me places I didn't have enough aero at and were I had to much.
Appeal to Authority is a logical fallacy and unscientific. You'd think people with "qualifications" would know that. Universities have truly failed to live up to their historical levels of prestige.
Just bought the book, the price looked most reasonable to me considering the quality of information in it, and moreover the writers ability to impart that information on to the reader. In fact I'd go as far as to say, it's a bargain.
Nice reply to the questions. My question is where is some info on the human powered vehicle stuff that you've done? I love me some good HPV videos and info.

they weren't trained engineers either. yet they were the most scientific and invented how we use wind tunnels today and created the field of aeronautical engineering. And their work was so amazing it took over 5yrs for anyone to catch up to them. They created the modern propeller (98% efficient too), created a cutting edge lightweight gasoline engine, invented the Angle of Attack indicator, 3-axis flight controls, etc.
Hey Julian, I've been watching your video for a few years and I have a question. Here is its basis/context. When a tire rotates it (generally) produces an area of high pressure at the top inside of the wheel well. We see that on many racing cars vents are added to the top of the wheel well and front corner panel to vent this high pressure air. However, on road cars this isn't usually done and adding them would require cutting the front panel. Question then: Would a narrow duct or tube than runs from inside the wheel well down and to the slight rear of the wheel well, exiting at the side of the car be utilized to vent this high pressure air? The fast moving air travelling over the rear facing exit of this tube should create a sucking force, combined with the high pressure air present at the entry of the tube, in the wheel well, to pull this high pressure air out? (Think of a flatish-tube, maybe 15mm in height by 100mm in width. unsure how far it would need to run back. We can worry about tire-wake and boundary layer issues later.. if possible.)
@@JulianEdgar I mean, standing next to my car it would be possible to create a slim-form rectangular tube that runs from the top inside of the tire well to the outside while hugging the surface of the vehicle. It could be done, on my vehicle, and not be impacted by the tire when the suspension compresses. I am afraid I don't know what you mean if otherwise. Not currently worried if it is ugly as sin for now, just curious if the pressure forces are there enough for it to be possible even in theory.
Measure the pressures, don’t guess or go by rules of thumb. Anyone can develop whatever theories they want, but measuring tells you what actually is happening. Your comments have a lot of guesswork in them. Don’t guess - measure.
@@JulianEdgar very true, just wondered if you had an opinion on the idea in general terms. But yes as complex as aerodynamics is theory and guess doesn't usually go far.
Any guess by me would be seen as an endorsement of your theory - not good. Here are some questions for you to think about. How do you know what the pressure is in the upper part of the wheel housing of your car? How do you know that that is bad? How do you know what the pressure is at the end of the proposed duct? What aerodynamic characteristic of the car are you trying to improve? Is your proposed route the best way of achieving that changed characteristic?
It’s sad that you have to make a video explaining your credentials. Anyone watching your videos should be able to discern that. People don’t want to hear all they need is a stiffer rear sway bar and to properly maintain their vehicles first

No, and I'll tell you why. If you look in the book, you'll see there are something like 200 graphs and diagrams in colour. I simply couldn't have run those graphs and diagrams in B&W, even though printing the whole book in B&W would have reduced the cost.
Have a mechanical engineering degree; would reference Julian's work
Engineering is about experiments and data.

I am a qualified mechanical engineer and whilst it helps, my experience has been 95% at the least, about what I have learnt.
The old claims about authority who believe that inventions flows out of universities.

Keep up the excellent work J
Thanks, will do!
Joe who has no qualifications: "You don’t have any engineering qualifications, so why should I believe you?"

The mindset of an engineer is different than a self-taught tinkerer. For your demographic, having the latter mindset seems like a better fit
Nice reply to the questions. My question is where is some info on the human powered vehicle stuff that you've done? I love me some good HPV videos and info.
I cover two HPV suspensions in the book.

The Wright brothers didn't have pilots licences
Hmm, not surprising. But they also had no formal engineering qualifications! Amazing men.

Do 10 minutes of measurement and you’ll likely change your mind about a lot of what you’ve said…
