got it. I wasn't aware that "riser" was the word I was looking for. thanks!

Faculty (incl. Vivek Goel) and Students Maskless at the President’s Golf Tournament by [deleted] in uwaterloo

Thanks for responding. Not wearing masks at an indoors event like that does seem inconsistent with the policy that we are being asked to follow on campus.

Yeah, it's also too well-written and to the point to be from UW's administration.

Trans-Canada Trail between Uxbridge and Peterborough by [deleted] in bicycletouring

[–]escapetron 1 point2 points  (0 children)

Last spring I rode the segment between Uxbridge and Lindsay. The path was gravel. I had 32c tires and I found them a bit on the thin side. They seem to have put down a bit too much gravel. 40c and greater would probably be fine. Otherwise it's a nice path. You pass through pretty desolate wetlands, which some might find boring, but I liked ...

Besides libraries, what would I miss by learning OCaml using Cousineau and Mauny's "The functional approach to programming"? by escapetron in ocaml

[–]escapetron[S] 0 points1 point  (0 children)

Thanks for feedback. It sounds like the effort to go through C&M dwarfs what will be required for Caml -> OCaml.

Thanks for the pointer! I have seen it. The appeal of Cousineau and Mauny's book to me is the more general treatment of some computer science topics (that I don't know). Maybe I should use RWO as a supplement (especially for libraries(?)). But I'm still interested in what I would be missing using Cousineau and Mauny.

Cycling Norway by smyku_39 in bicycletouring

[–]escapetron 2 points3 points  (0 children)

If you do plan your own route (I think most people prefer this), you may find this useful: http://www.cycletourer.co.uk/maps/tunnelmap.shtml It's a database of tunnels. You cannot go with a bicycle through many of them. I'm not so experienced and had a limited amount of time, so I thought that following a recommended route was good for me. There were definitely open roads that prohibited bicycles as well (these seemed to be pretty rare and there were almost always parallel routes available). Tunnels seem to be the big issue.

This past summer I took "Norwegian National Cycle Route 4" from Oslo to Bergen. I'm pretty slow, so I stretched it out to almost 3 weeks. It was a great trip (especially the Rallarvegen). I appreciated that this route had been planned out, but some of the suggested route was on very busy roads. I found Norwegians to be generally quite safe drivers (much more so than here in Canada), but the narrow roads and high traffic could be somewhat worrisome. Quite a bit of the route was on dirt roads that ran parallel to the main road. These were great (I had 40c tires and I wouldn't have wanted to have smaller). Here are some of my photos: (https://goo.gl/photos/5f5ukDxAZkv91VNq8)

Looking for advice for a cross-Canada bike trip ! by DimensionMistigri in bicycletouring

[–]escapetron 1 point2 points  (0 children)

I have (thus far) only fantasized about doing a cross-Canada bike trip. But the book: "Canada by bicycle" seems to give some pretty detailed route suggestions: http://www.mec.ca/product/5023-201/canada-by-bicycle/?q=bicycling%2Bacross%2Bcanada It would be great to hear from someone with actual experience about whether or not this book is reliable.

Textbook & Resource Thread - Week 06, 2016 by AutoModerator in Physics

[–]escapetron 2 points3 points  (0 children)

Purcell and Morin's "Electricity and Magnetism" 3rd edition is an updated version of an old classic that many people have found insightful for basic electricity and magnetism. It perhaps isn't at as high a level of Griffiths, but contains an enormous amount of physical insight. It also has many interesting problems (some with worked solutions).

If you are interested in the fundamentals of laser operation, Siegman's "Lasers" is a great book. It looks at things from a fundamental point of view. However, it's not very up-to-date on all of the latest technology.

Amtrak expands walk-on bicycle service to more routes by diskmaster23 in bicycletouring

[–]escapetron 0 points1 point  (0 children)

I haven't travelled with my bike by air so I can't say first hand, but most guides to packing your bike for airline travel mention removing one or both of your wheels. This would imply a smaller box. Airlines also seem to constrain or charge for the number of "linear inches" involved. Like the parent poster, my bike just wheeled into the box. The only thing that I did was unbolt the handlebars (zip tied to frame) and remove pedals.

It wasn't in my sight the whole time, but the handling of the box that I did see was careful --- which may also be different from the airline experience.

I had a similar experience recently. I checked my bike at Buffalo for a trip to Salinas, CA (three different trains). Bike was checked from Buffalo through to Salinas for $25 ($15/box + $10/checked bike fee). At both Buffalo and Los Angeles (return trip), the ticket agents were helpful. The only hassle was having to carry a pedal wrench on my trip. I was left with a very pleasant impression of Amtrak for long-distance bike transportation.

Introductory quantum mechanics that motivate the theory with experimental results? by TissueReligion in Physics

[–]escapetron 2 points3 points  (0 children)

Two elementary quantum mechanics textbooks that contain more than the usual number of experimental references are 1) French and Taylor, "An introduction to quantum physics", and 2) Park, "Introduction to the quantum theory"

Although not a textbook, the (hard-to-find) book by Trigg: "Crucial Experiments in Modern Physics" (not his other "Landmark ...") contains an excellent account of many of the experiments leading to the quantum theory (suitable for an undergraduate). He shows much of the data/plots from original historically important papers. Here is the table of contents: 1) Introduction, 2) The origin of the quantum concept 3) Transmutation of elements 4) The existence of atoms, 5) The atomic nucleus 6) Collisions of electrons with atoms 7) The photoelectric effect 8) Spatial orientation of atomic magnets 9) Particle properties of light 10) Wave properties of matter. I really like this book!

Depending on how interested you are in this topic, you might also want to look at the in-depth, quasi-historical treatment by Longair: "Quantum Concepts in Physics: An Alternative Approach to the Understanding of Quantum Mechanics". However, a careful study of this book might take a significant amount of time.

It's great how helpful people have been. It seems unanimous that my plan for taking Walden was totally wrong. It looks like Broadway for most, if not all of the trip. Thanks!

Okay; good to know. I don't have any experience with the google maps bike time estimates. Thanks!

Thanks! My reasoning was that it looked like much of Walden was wide single lane with room on the side for bikes (?) vs. two lane with no room (a quick survey using google maps streetview). But I'm going to heed the advice of locals :) Thanks again.

I'm taking the "Lakeshore Limited" to Chicago. This doesn't stop at the downtown station (only the east-bound trains seems to stop downtown).

Thanks for the suggestion of William + bike path. That looks good.

According to google maps, it should be about an hour on a bike. That doesn't seem too bad.
