I love the bicycle topics! I run my own bike repair shop out of my garage, and almost none of my customers properly lubricate their chain. It's good for business though, because when people ride their bike again for the first time after servicing, it feels like a totally new bike to them, and I get good reviews!
Pretty lame
Chain waxer here (immersion waxing)✋
For riding in the dry, wax is just the best. The chain stayw clean for soo long.
For riding in the wet, wax is also the best, it just doesn't last as long.
23:28 there is no YT-channel "Will It Lube", but basically what they are describing is the channel "Zero Friction Cycling" which compares many different lubes with extensive tests that are as close to real world as possible while still being repeatable. He often gets quite chatty, but the website is very good when you look for some good lubes (and yes: all top spots are claimed by wax). I have to confess that I still use a wet-lube, but after I had a lot of troubles with some well known brand (that he also had quite bad results in his tests), I switched to a brand that fared well in his tests and the difference is night and day for the intervals in which I have to clean&lube. So recommendation: If you don't want the hassle of waxing your chain (I know it supposedly isn't as bad as it sounds), at least buy yourself a good wet lube!
Lies
What's your initial cleaning like? Some really advocate the shaking in gasoline, ultrasonic can be good if available, anything best?
Also additives, some are questionable, both in actually helping but also the potential dangers to self and environment.
There’s a company named Park Tools that specializes in bike tools and lubricants. I see a definite opportunity for a sponsorship - Matt Parker Tools Around.
Parker Square Bolt
Love Park Tools videos so much, really helpful for learning bicycle maintenance
I wrote a book in about 1982 to explain the X25 data communications protocol - it was called X25 Explained! Does what it says on the tin and (almost) alliterative. My first book had a less snappy title - A practical guide to computer communications and networking. It sold less well!
The intro of "only murders at the building" is different every time and gives hints to the episode.
My favorite digit is 3, maybe because I always write them with a flat top and that stroke is so satisfying. I don't really like 2s much. Oh, and I love text figures ("lower-case" digits), and prefer them in running text or prose, especially when they match a good crisp serif font where they are used. Not only are upside-down 8s very annoying, upside down 6s and 9s are likewise (in some fonts you can tell)
sedimentary, igneous, & metamorphic triangles - hilarious (& mebbe daunting)
I saw a double rainbow today and it was more enjoyable after reading Love Triangle
Loved the Parker Frames of the video
grease the chain with heavy grease (not lube nor wax) and unless you are in a REALLY dirty environment (like dusty deserts, muddy mountains, filthy forests and such.), i.e. city biking, you do not need to clean the chain - ever. doesnt care about rain, doesnt care about sun, doesnt care about light dirt. doesnt care about heavy gear switching.
if you are not a fan of ruining your white dress, you can use something like graphene based lubes, but with a proper chain guard, thats just unnecessary.
the big con is ofc its not "clean" looking, though depends on your grease type and color / cover. what you dont see, dont need to look good.
and this is for normal-people-bikes. no e, no high speed, no special outdoor. normal, everyday use.
as for the "but it might increase friction" argument: nah. on normal bikes, more friction is generated by your tires (ofc. heavily depending on your type) and the gears / tire axis. the chain itself adds practically nothing.
That's just not true. The metal-on-metal grinding will wear out a chain. Even perfectly lubricated and kept in a dust-free environment. It will take longer, but it will wear. And with the wear, it will elongate and eventually ride too high on the sprockets and start to fall off or jump, which can be disastrous if it happens at the wrong time.
I liked and sort of embraced Pythagoras and the basic trigonometry. It's so hands-on and actually useful sometimes.
(Maybe more emphasis should be put on making the students *familiar* with different corners of math, so that they are likely to go there with some onfidence later.)
Digits: Lining or non-lining, and tabular or proportional.
Love me some Matt Parker.. will we see a tim cameo in a future numberphile/standupmaths?
Speaking of bicycle chains, they don't last very long. They will "work" forever, but should be replaced surprisingly often. Before there's a problem.
depends on your chain type and your usage. a heavy chain on a citybike is practically unbreakable.
a superlight on a dirt / mountain bike, might need to be replaced / checked like twice a year.
First! Always feels good to do that.
Why the parker square at 23:00 ?
It’s not just at 23
