Getting back into graduate level math after extended illness.

I have persistent post concussion syndrome and after being over worked/ over stressed I became unable to think well from mid February until a week or two ago. Prior to this I had been learning a lot of algebraic topology, differential geometry, and algebra and now I’m wondering what is a good way to go back and review the material to get me back where I was before I became sick.

The books I was using were Hatcher’s, May’s, Lee’s (deferential and Riemannian), and Allufi’s

Cars Canada has that the United States doesn’t

  • Acura CSX

It is basically an eighth-gen Honda Civic Sedan with a different grille. Before the CSX was the EL. Nothing that important.

  • Asüna brand

They were basically just the Geo of the north except they got a cool rebadged Pontiac LeMans called the Optima SE and Optima GT. They also made the Sunrunner and Sunfire and originally the brand was called Passport.

  • Chevrolet Epica

Not too special as it is a rebadged Suzuki Verona which we received in the United States. But it is still pretty nice lookin’. Sorta.

  • Chevrolet Optra

Based of of the Lacetti (which wasn’t sold here, and if it somehow was, I’ve never seen one) is the Optra. It was sold in Canada and in China it was the Buick Excelle and in the Land Down Under it’s the Holden Viva.

  • Chevrolet Orlando

I don’t get it, Chevy. You are going to sell an MPV in Canada named after a US city without it actually selling there. Please explain.

  • Hyundai Accent Hatchback

We did have the Accent Hatch, but it was killed when the Accent was redesigned. They have a nice new one in Canada, though.

  • Kia Rondo

The older one sold in the US but not the sleeker newer one. Canada just doesn’t want us to have a decent compact MPV. Shame on them.

  • Lada brand

Yes, in the older days of Canada they sold those boxy Lada cars. Primarily just the Niva and sedan things (honestly I forgot the name).

  • Mercedes Benz B-Class (first generation)

The first gen MB B-Class was pretty ugly and weird so I can see why they didn’t sell it in the US. It just didn’t appeal to us I guess. Neither did the newer (now dead) ED one.

  • Nissan Micra

The Micra is a cute little hatch that is sold pretty much everywhere that has Nissan. Except for USA, though. Hopefully we get the redesign when Canada does.

  • Nissan X-Trail (first-generation)

The newest X-Trail is sold as the Rogue in the US. Kind of a bummer we missed out on the older X-Trail but if it were a newer car (like the Micra) we were missing out on I would be more disappointed.

  • Pontiac Wave

Basically an Aveo (Hatch and Sedan) with a Pontiac badge. Nothing too special in my opinion.

  • TVR brand

Yes. They sold TVR in Canada. Let me guess, everyone is heading north now? Okay I think so. WAIT! I AM COMING WITH YOU!

Mountain driving

I recently moved to the top of a mountain with steep winding roads, and could use some help with driving advice. I know the basics (don’t ride your brakes all the way down the mountain, use pull outs if theres faster trafic) but could use some more advice. I usually just coast on the way down and brake going into turns, but that’s still ware on the brakes. I know theres a way to slow yourself down by switching from automatic to manual transmission, but I’m not sure exactly how that works or when I should use it. Any advice would be appretiated. Also, I drive a 2014 Mazda 3 in case that’s important.

Practical Applications of Complex Analysis

I’ve been looking at complex analysis, particularly the Riemann Zeta function and the Riemann hypothesis. It caught my attention and I’m interested in studying it, but I’m looking for fields to apply it to.

Is there any practical application of complex analysis yet, in science, or is it just theoretical mathematics?

I really want to see a revival of American personal luxury cars.

Cadillac could make a camaro or impala coupe. Ford could make a continental coupe. Chrysler could make a luxury challenger. The American luxury Segment is faking because we are trying to be Europe. BMW is always going to be better at creating sporty sedans so why even bother. If Cadillac tries to be Cadillac instead of being a knock off bmw, then they would sell.

1976 coupe devile base price: 41,000

Cadillac CT6 base price: 54,000

6 Series

E Class

Can you use statistics about Nevin Manimala to forecast budgets?

Hello, I work for a company where we bid out projects but do our own internal estimates first to roughly gauge the costs. Lately we’ve been finding our internal estimates are way off from the bidders and I’ve been tasked to help understand why this is.

However, I’m unsure of how to go about this and we only have a history of roughly 20-30 projects. Can you please give some advice on a) whether this is a feasible effort given the small population size and b) if it is possible, how best to go about determining how and where our estimates are off (we already know that our management and quality control estimates differ wildly from the bidders‘ proposals)

Chevrolet Evanda rear suspension looks funny

I recently bought a 2005 Chevy Evanda, and something about the rear suspension visually feels off. There’s a part of it that hangs over the tire in the wheel well with a bolt suspended about 2 inches above the wheel.


Feels completely fine driving, but i can’t shake the feeling if I have it even somewhat moderately loaded and hit a sharp bump, that bolt is going to tear the tires apart.

Never seen anything like it in any other car. Anyone know if it was originally designed this way or if there were possibly any modifications done later?
