Today I felt a bit bored.

I decided to modify and mod one of the first thing I learnt to solder : a voice changer Velleman kit.

Now, it's a pretty decent fuzz/glitch/octaver/noise pedal.

It's made for true noise purpose. It works.

I'm terminally humanities brained, but I am kind of interested in pure mathematics and POM and generally just more mathematics oriented philosophy stuff/mathematics in general, I haven't studied any kind of maths since Highschool, how should I get into it? Should I read Quine?

Oh, this is a great question and I am very happy you have decided to send it to me! My answer reflects my particular views on mathematics and what it is all about, of course, so keep that in mind.

The number one thing I would like to convey about mathematics to someone coming from the humanities is that mathematics, far more than most fields, is something you do in addition to something you learn. Mathematical thinking has to be practiced, it is a skill that you train. If your primary interest is in philosophy of math, I'm afraid I haven't read very deeply on the subject and probably can't recommend a good starting place. Maybe... Russell? Look into Hilbert's program, and why it failed? But if you want to understand math "from the inside" instead of "from the outside", then you have to do math, and to that end I think "who to read" is the wrong question.

This might sound a bit scary, but I don't think it needs to be. Math is not so hard to do, although it is a very foreign type of thinking to those who are not practiced at it. In fact, this is why I think doing math is important even if your interests are primarily in POM; math is ultimately a human activity, regardless of e.g. what you believe about the ontology of mathematical abstractions, and I believe that in order to understand it fully (to have a picture of it beyond just its ontology) it must be understood as a human activity. Thus, one must do it, at least a little bit. It is, if nothing else, a whole realm of human experience all its own, and I think just about anyone would profit intellectually from spinning their mental gears in a mathematical way here and there.

Thankfully, there are many great places to start if this is your aim. I assume that what we're talking about here is "proof based" math rather than just calculation. To that end, a great introductory book is Velleman's How to Prove It, which will give you some guiding principles and many examples of how to approach a mathematical proof. Beyond that, I think you'll want to pick up an "entry level" introductory text (that is, an introductory text aimed at undergrads, etc.) on any math topic that strikes your fancy, and work through it—making sure that you understand the structure of the arguments (proofs), and attempting as many of the exercises as you can. The exercises are really the most important part. You cannot learn math without the exercises. You cannot learn math by reading it. The only way to learn is to try your hand at it yourself.

Expect your reading speed to be slow, and new concepts to be confusing. Expect to read things over and over, and fiddle with them in your head, before they make sense. Well, I mean, if you're anything like me or like most people. I think one of the biggest reasons people get turned off to math is that most of it just doesn't make any sense the first time you encounter it; it won't make sense until you've thought about it a lot.

One way or another, if you have a background in philosophy and are used to parsing and evaluating careful arguments, you will have a leg up on many people getting their introduction to proofs.

As for what topic to start with... you could always start with Euclid's elements, which is still a perfectly solid introduction to Euclidean geometry even after 2500 years. It does not quite meet modern standards of mathematical rigor (in other words, its proofs have gaps by modern standards), but realistically this is not a big deal: the basic thinking style is the same, and the gaps are somewhat subtle and technical IIRC, so I don't think it will really affect the beginner experience. On the other hand I believe at least a couple of Euclid's proofs are genuinely flawed (that is to say, they aren't just uncareful in their presentation, but are actually invalid in their structure), so maybe it's better to start with a modern work first.

Some books that I think are good for a beginner:

Graham, Knuth, & Patashnik, Concrete Mathematics — The focus of this book is on mathematical tools for computer science, but even if that is not your interest it's still a great book. It deals mostly with familiar concepts such as whole numbers and sequences (you might have encountered, e.g., the Fibonacci sequence), but is great for learning to problem solve and think mathematically.

Rudin, Principals of Mathematical Analysis, ("Baby Rudin") — If you want trial-by-fire. A lot of math undergrads have this as the textbook for their first proof-based math class, and it's notoriously challenging. Its topic is the field of real analysis, the rigorous foundations of calculus. I... wouldn't start here if I were you, honestly, but it's definitely a classic.

Some graph theory text. Some people seem to be recommending Wilson's, which has the convenient feature of being available online here. I haven't read it, but looking over it, it seems fairly gentle. There are a lot of pictures, and proofs don't enter the picture until a couple of sections in. Graph theory has the advantage of being very visual and having basically no prerequisites, so this might be a nice place to start.

Some abstract algebra book. If you're looking for a really clear presentation of the way mathematics is done today, starting with axioms and proving theorems deductively from them, etc., there is probably no place where it is more straightforwardly visible than in abstract algebra. The first math book I ever attempted was Herstein's Topics in Algebra; not the most beginner oriented, but certainly not inaccessible, and hey, it worked out for me! If this one is not to your liking there are a million books on e.g. introductory group theory you could look into, or the very canonical Dummit & Foote, or so on.

Uh yeah I think that's all I got. Anyone else feel free to put any more thoughts or recommendations in the reblogs!

I keep forgetting to take pictures before or while I'm building kits.

This one was a Velleman MK119 Roulette Wheel — 37 LEDs in a circle, with an animation and spund effect that picks one at a button press; 18 of the LEDs are red, 18 are green, and one (labeled 0) is yellow.

I found the kit at a thrift store for about $4, and decided to take out all the pieces to sort them and check if any were missing, which led me straight into impatience and building the whole thing over the next hour or two. (I should also check the clock more often.)

Here's my assembled unit, on the paper I'd taped the parts down to; below is a manufacturer photo of all the pieces.

Anyway, this is what I do instead of sleeping sometimes.

Een vertrekkende trein (met loc 2245) maakt de 'oversteek' op het Marconiplein, 20 mei 1967. Het afgebrande gebouw is de oude politiepost.

Naamgever van dit plein is Guglielmo Marconi, 1874-1937, uitvinder van de draadloze telegrafie.

Na de aanleg van de Koushaven, IJselhaven, Lekhaven en Keilehaven werd in 1914 begonnen met de bouw van een nieuw emplacement langs de Hudsonstraat in de wijk Bospolder/Tussendijken. Dit emplacement was 14 sporen breed en werd overbrugd door een loopbrug vanaf de Hudsonstraat naar het havengebied van de Vierhavenstraat. Dit emplacement stond bekend als Rotterdam RMO (Rechter Maas Oever).

Na de aanleg van de Merwehaven werd een emplacement langs de Schiedamseweg/Rotterdamse dijk geopend. Dit emplacement werd op het laatst voornamelijk gebruikt om de in de Merwehaven aanwezige fruitbedrijven te bedienen. Jarenlang heeft er een rechtstreekse trein gereden tussen Spanje en Rotterdam (41815), waarmee wagonladingen sinaasappelen werden aangevoerd naar bedrijven als Velleman en Tas, Henk van den Berg en Zoutewelle. Maar er waren ook veel andere klanten. Beroemde Rotterdam havenbedrijven als Müller, Swarttouw en Quick Dispatch hadden er een spooraansluiting, en er zat ook een aantal olieopslagfirma's. Aan het westelijk einde lag de aansluiting langs de Gustoweg, waar de firma van Uden kolentreinen loste afkomstig uit de Sophia Jacoba mijn in het Duitse Hückelhoven. Deze kolentreinen waren ook de laatste treinen die gebruik hebben gemaakt van de nu verwaarloosde goederenlijn tussen Roermond en Dalheim, de IJzeren Rijn. Van het spoor langs de Gustoweg is nog steeds een deel aanwezig, netjes afgezet met hekjes.

SOLUTION AT Academic Writers Bay Book name for the Cours Stats: Data and Models (4th Edition) (Hardcover) by Richard D. De Veaux, Paul F. Velleman Question 1. Re-expressing Data to Fit a Linear Model Suppose that you have the following data below for x (the independent variable) and y (the response variable): independent.var = c(5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60) response.var = c(16.3, 9.7, 8.1, 4.2, 3.4, 2.9, 2.4, 2.3, 1.9, 1.7, 1.4, 1.3) A) Using a linear model, fit a line to the above data without using a re-expression. Show the fitted line relative to a scatterplot of the data. Comment on what you see in terms of fit, and also calculate and explain the meaning of R2. B) Re-express the data so that you obtain a better linear fit, and explain how and why you chose your re-expression. (NOTE: Only consider re-expressions that change the y-variable (the response variable, for this problem). Also, show the re-expressed fitted line relative to the re-expressed data. Comment on what you see in terms of fit, and also calculate and explain the meaning of R2. Question 2. Simulation – Washington Nationals Win The 2019 World Series. As we all know by now, the Washington Nationals beat the Houston Astros to win the 2019 World Series. However, before the start of that World Series, the Washington Nationals were often cited as having only a 40% chance of winning any particular game against the Astros. So, how rare is what the Nats accomplished by winning the 2019 World Series? Let’s pretend that the World Series has not been played yet. Keep in mind that the World Series is a series of up to 7 games. The winner is determined by whichever teams wins 4 games first. So, the World Series may last only 4 games, or perhaps 5 games, or 6 games, or even 7 games. The World Series is over as soon as one of the teams wins 4 games. Run a simulation using the above information to assess the chances that the Washington Nationals win the World Series. Make sure that you show all of your work, including anything you do in R (e.g., any random numbers you generate and how you use them). In doing so, make sure that you specify how you are modeling the simulation using equally likely random digits, explain what constitutes a trial and its outcome. Run 25 trials, where a single trial is the simulated result of a single completed World Series. Show your results of all 25 trials and the random numbers you used for each trial. Finally, provide the results of your entire simulation – that is, state what your simulated estimate is of the likelihood that the Washington Nationals (the team with the 40% chance of winning any specific game in a series) wins the World Series – and show details of how you got that estimate. Question 3 Nutrition Surveys: Eat This, Not That…Oh, Never Mind As mentioned in a very early lecture, one purpose of this course is to allow people to become more informed readers of news articles, and to be able to critically assess and compare different viewpoints. I referred to this as becoming more “numerate.” Nutrition advice seems to be quite inconsistent over time. There are some reasons for this, as the article link below explains. Please carefully read the link below, and then proceed to answer the questions posed. https://slate.com/human-interest/2015/04/nutritional-clinical-trials-vs-observational-studies-for-dietary-recommendations.html Provide detailed answers to the three questions below: A) List and explain at least 3 major weaknesses of nutritional studies as cited in the article. B) Suppose that we want to study whether or not a particular food causes a particular health issue. In this example, the health outcome is the response variable. In particular, suppose we want to study whether sugary soft drinks cause obesity in adults over the age of 18. State how you might design an experiment to better determine causality (or not). Be detailed in your design explanation by specifically focusing on

the relevant features of Four Principles of Experimental Design in your response (see pages 321-322 of the text). Also, explain how you will measure both the independent and response variables in this experiment. Question 4 Probability Rules – Must show all needed steps in getting to your final answer. And, express your final answer as a decimal. A) Assume that for events A and B we have the following: P(A) = .40, P(B|A) = .20, and P(B) = .30. Find P(A or B). B) Suppose that P(A) = .40, P(B) = .30, and P(A and B) = .15. Are A and B independent events? Why or why not? C) Suppose that you are planning to travel a certain air route via plane once each week for your new job. Also, assume that there is a 3% chance that your outbound flight may be cancelled on any given week due to various issues. How many consecutive outbound weekly flights can you fly before the probability of another successful flight (that is, a flight that is not cancelled) drops to 50% or less? D) Suppose that 20% of cars that are inspected have faulty pollution control systems. The cost of repairing a pollution control system exceeds $100 about 40% of the time. When a driver takes her car in for inspection, what is the probability that she will end up paying less than $100 to repair the pollution control system. E) Assume that you are playing a game in which you pull a lever and a light comes on. The light will be either red or green. Assume that on any given pull of the lever, P(Red Light) = .40 and P(Green Light) = .60. Find the probability that in pulling the lever 5 times that you will get your 3rd Green Light on the 5th pull of the lever. F) Suppose in front of you are three boxes that look identical. Further, you are told that one box contains two $1 bills, one contains two $100 bills, and one contains one $1 bill and one $100 bill. You are permitted to choose one box. Then you are asked to remove one bill from the box you chose without looking at the other bill in that box. Suppose that a $100 bill comes out. What is the probability that the other bill in that box is $100?   “CUSTOM PAPER” CLICK HERE TO GET A PROFESSIONAL WRITER TO WORK ON THIS PAPER AND OTHER SIMILAR PAPERS CLICK THE BUTTON TO MAKE YOUR ORDER
