      A few corrections based on my suggestions already... 😁




    1. Since one cannot prove that it is inaccurate, you cannot discount its possibility.

      False. Per Hitchens's Razor, "what can be asserted without evidence can also be dismissed without evidence."

      Put simply, the responsibility for proving a claim rests with those making the claim. One may safely discount the possibility of anything that cannot be proven.

    1. Like all plants, the bulrush requires oxygen to produce energy. One solution is obvious: Send shoots skyward like straws to suck down oxygen to the roots.

      Plants don't require oxygen to produce energy (photosynthesis), they require CO2.


      Oxygen is generated as a byproduct of this, not a requirement.

    1. Repeat process until vehicle.

      I guess it's not a vehicle until you buff it repeatedly with Rain-X products.

    1. Russian armored vehicles are loaded onto railway platforms

      They are loaded onto railway flatcars. The platform is the area in the photo marked by white lines - where passengers board trains.

      Journalists know very little about the world around them yet present themselves as authoritative.

    1. The YYY gate is similar to the XXX gate, but instead of 111s on the off-diagonal, it has iii and −i-i−i, so it takes ∣0⟩|0\rangle∣0⟩ to i∣1⟩i|1\ranglei∣1⟩ and ∣1⟩|1\rangle∣1⟩ to −i∣0⟩-i|0\rangle−i∣0⟩:

      Question for the creators: https://i.imgur.com/9XUDZPH.png

      I thought the answer to this was "both" since 0 is obviously a real number.

      Can you help me understand where my misunderstanding is?

      Thanks so much for creating this tool. I've been having a blast learning!

      Further, I am grateful to the following people for telling me about errors and typos in the hardback edition: Nimrod Priell, David Marker, Giannis Kanellopoulos, Hiroki Takikawa, Jun Tsunematsu,Takuto Sakamoto, Shinya Obayashiand, Anna Ballarino, Arthur Spiriling, and the hypothesis user named arnaud.

    1. Figure 4.3: Schematic of the experimental design from Schultz et al. (2007). The field experiment involved visiting about 300 households in San Marcos, California five times over an eight-week period. On each visit, the researchers manually took a reading from the house’s power meter. On two of the visits, they placed doorhangers on each house providing some information about the household’s energy usage. The research question was how the content of these messages would impact energy use.

      In the figure, "3 week" should be "3 weeks"

    1. Figure 3.7: Demographics of respondents in W. Wang et al. (2015). Because respondents were recruited from XBox, they were more likely to be young and more likely to be male, relative to voters in the 2012 election. Adapted from W. Wang et al. (2015), figure 1.

      In the x-tick marks in the panel titled "State", Obama should be capitalized and Romney should be capitalized.

    1. 10–27

      Equation 10-27 is wrong:

      • Resistors are in parallel, their noise does not sum.
    2. Adding this and the 100-kΩ resistornoise to the amplifier noise

      This is 3 terms (10 MΩ noise, 100 kΩ noise, and amplifier noise), but the equation only includes 2.

    3. 10–25

      Equation 10-25 has several errors:

      • The left and right side are not equal.
      • Resistors are in parallel, so their noise does not sum.
      • Resistor noise needs to be multiplied by gain to be combined with 113.1 μV output noise of op-amp.
    4. 10–23)

      Equation 10-23 is incorrect:

      • The noise of the resistors does not sum, since the resistors are in parallel and load each other. It would be equal to a single 50 kΩ resistor producing 4.0 μV.
      • The 113.1 value is output noise. The resistor noise needs to be multiplied by the gain to get the output noise, too.
    5. 0.1 F

      Should be 0.1 μF

    6. 0.1 F

      Should be 0.1 μF

    7. The noise calculations have many errors. See annotations on https://via.hypothes.is/http://web.mit.edu/6.101/www/reference/op_amps_everyone.pdf for details

    8. which is 100

      actually should be multiplied by the non-inverting noise gain, which is 101

    1. To deal with this by using exceptions, we're going to take advantage of the catch function from System.IO.Error

      The catch function is deprecated and when I tried this with ghci 7.10.3 got an error that System.IO.Error does not export catch. The replacement is the catch function in Control.Exception

    2. The bytestring version of : is called cons It takes a byte and a bytestring and puts the byte at the beginning. It's lazy though, so it will make a new chunk even if the first chunk in the bytestring isn't full. That's why it's better to use the strict version of cons, cons' if you're going to be inserting a lot of bytes at the beginning of a bytestring.

      I initially did not see the difference in the output of B.cons vs B.cons' here, both output a plain string.

      I think this is because of the Show typeclass implementation for Data.ByteString.Lazy which is used by ghci when printing values.

      If on the other hand I use :force <expr> which fully evaluates <expr> and prints out the resulting structure then I do see the difference.
