Bike journo doesn't do physics shocker

onewheel, I was a regular on rec.bicycles back in the mid nineties when the actual web only had about 4 pages on it and everyone wondered what the fuss was about, and the like of jobst brandt, sheldon brown, gary helfrich, keith bontrager would chip in on any and all topics. Funny to see the same topics revisited ad infinitum.

Jobst might have an analytical mind and access to computer modelling, but he was also totally adamant that it was impossible for a thorn to puncture a tyre 😯 , or for a cycle to recover from a 2 wheel drift. Watching motogp qualifying as I type….

Mark, your introducing yourself as “a member of the institute of physics” makes you way more insufferable than aracer IMO.

Bike journos hat been getting very basic stuff wrong since time began, and I’ve seen much worse.

ANyway, back to the OP. Your explanation is good, however I think you are wrong, having missed out a crucial point:
The wheel’s rigidity is not directly proportional to spoke tension. This is because as tension increases, a laced wheel’s spokes bed in-both to the hub flange and at any cross. More bedding in means more stiffness.

No probbly best not actually… 😮

Hahahahahahaha!! Classic!

Pwned like a biatch…

ISTR people making the same argument on rbt – to which JB’s response was invariably that a bicycle on tarmac (with skinny tyires) wasn’t a racing motorbike.

From the days before the web even existed. Incidentally many of the big hitters from rbt joined a mailing list called “Hardcore bicycle science” when the signal to noise ratio on the newsgroups dropped too much – something which itself is now defunct. Sadly I don’t think there is anything equivalent nowadays.

Ah.. Al and Bull, my two most loyal fans ..

Hi guys 🙂

WTF? Nothing personal at all!…If you can’t take a flaming…

Anyway aracer: no response? Oh dear…

Awww, c’mon Mark; even you have to admit that an opening gambit of;

…as a member of the Institute of Physics

you sound like a total plum.

You’re an ex-physics teacher right? Tell me you didn’t bandy that one around in the staff room in order to win an physics-related argument did you? The PE department would’ve eaten you alive….

EDIT: For the record, Al and I haven’t consulted each other on the agreed idiocy of your initial opener; rather we came to the same conclusion as two individuals.

Former physics teacher LOLs!

The PE department would’ve eaten you alive….

FFS and you think he sounds like a tool 😯

Those who can do. Those who cant teach. Those who cant teach teach PE

(Feels somewhat left out. Is really quite upset)

Those who cant teach teach PE

Badge. Of. Honour.

Interestingly, over 88% of school leaders are ex-PE. Less than 0.073 are physics teachers. Fact.*

*This fact is probably true.

Ah, that old debate. Which requires more intellect, rounders or general relativity.

As for the OP, do you have a cape as well as super pendant powers?

Ace! 😀

Elf; you put the picture up?

For me?

some that can still teach 🙂 🙂

Only for you, Bully. 🙂

X

over 88% of school leaders are ex-PE

see only PE teacher would post up “evidence” of people who dont teach to prove they can teach 😉
I though the highest was from History FWIW.

All about the win Mr Yard; all about the win…

I was at a conference a year ago when they mentioned a ‘stat’ regarding School Leaders and their respective ‘disciplines’. Whilst it’s not the percentage I stated, I’m led to believe that ex-PE staff lead the field. Typically though, when it was declared, an audible ‘yessssssssss’ could be heard from several tables in the vicinity.

Haterz gonna hate 8)

The least uninteresting thing I’ve learned from this thread is that the swear filter doesn’t appear to work on tags. Wahey!

Mark, your introducing yourself as “a member of the institute of physics” makes you way more insufferable than aracer IMO.

Nah, not by a long way.

Ooooh, another member of The Institute of Physics.

Do you have the O-level?

Hey! They have an affiliate membership for £88!

http://www.iop.org/membership/join/affiliate/page_51400.html

Al – with my knowledge of bone torsion in a range of proximal/distal bone lengths in obese children, and your studies into braking forces on balsa/carbon/tin foil bikes, we’re a shoo-in to be accepted!

😀

Well I was going to retain my modesty, but I have in fact studied Physics at university level, which I think would qualify me to teach it, so I’d prob be one of their most academic members (pun intended).

Is Professor Higgs a member? If lectured us. My GF used to swim with his Mrs-apparently he was a true geek/genius….would confess to thinking about particle physics during most activities.

I win teh PHYSICS NAME DROPPING CONTEST

I won the School Prize for Physics. So ner. Let me know when you need some sort of casting vote 🙂

STW is far, far less guilty of this than many others I’ve read

Sounds of furious backpedalling.

Hey aracer, you haven’t said ‘strawman’ for a good few threads; say it again and maybe someone will pick up on it.

Well, PE is Physical Education, so more or less same thing, no?

It was Chemistry I found really boring. I mean, it’s fun to blow stuff up, but when it gets onto all those equations and stuff, my mind glazes over and I get distracted by other things such as pretty pictures and ladies’ bottoms and stuff. 😳

I’m a member of the Ponds Institute.

Going by his Twitter it looks like we upset him.

At least he can do some high level physics as a stress buster right now.

but I have in fact studied Physics at university level,

Walk into the wrong lecture? We’ve all done that. I think I’ve studied economics at university level once or twice.

No, I sat honours level in first year, but my point was that it’s no big deal.

Maybe this might help Mark?

I think the link for the last one is broken though…

😉

😀

Hang on, you calling me a clown? 😡

Well, I’m sure you’ve bin called worse, Al. 😮

I’duv hated you as my PE teacher, Bully. I wooduv bunked off lessons. 😥

I might watch Tron Legacy tonight. Is it any good?

Not sure what to have for supper mind. Tomatoey bacony pasta is certainly one possibility…

Corrected.

I’m Irish! and is that Fred a combo of “mini and amateur”?:D

I’m about to cook some steak for a lovely lady. Yeah, the lucky one that got the Asda flowers 😎

Scottish, Irish, whatever…

Lady Sade. If ever a knighthood was deserved…

I find Barry White works best 😉

Hell; she could sooth even the grumpiest of IOP associates…

I read this on their web page:

If a pizza has radius z and height a, it’s volume is…..

pi.z.z.a 😀
