Nothing up my sleeve number
In cryptography, nothing up my sleeve numbers are any numbers which, by their construction, are above suspicion of hidden properties. They are used in creating cryptographic functions such as hashes and ciphers. These algorithms often need randomized constants for mixing or initialization purposes. The cryptographer may wish to pick these values in a way that demonstrates the constants were not selected for (in Bruce Schneier's words) a “nefarious purpose”, for example, to create a “backdoor” to the algorithm. These fears can be allayed by using numbers created in a way that leaves little room for adjustment. An example would be the use of initial digits from the number π as the constants. Using digits of π millions of places into its definition would not be considered as trustworthy because the algorithm designer might have selected that starting point because it created a secret weakness the designer could later exploit.
Digits in the positional representation of real numbers such as π, e and irrational roots are believed to appear random. See normal number. Such numbers can be viewed as the opposite extreme of Chaitin–Kolmogorov random numbers in that they appear random but have very low information entropy. Their use is motivated by early controversy over the U.S. Government's 1975 Data Encryption Standard, which came under criticism because no explanation was supplied for the constants used in its S-box (though they were later found to have been carefully selected to protect against the then-classified technique of differential cryptanalysis). Thus a need was felt for a more transparent way to generate constants used in cryptography.
“Nothing up my sleeve” is a phrase associated with magicians, who sometimes preface a magic trick by holding open their sleeves to show they have no objects hidden inside.

Antagony & Ecstasy: BLOCKBUSTER HISTORY: NOTHING UP MY SLEEVE
Every week this summer, we'll be taking an historical tour of the Hollywood blockbuster by examining an older film that is in some way a spiritual precursor to one of the weekend's wide releases. This week: combining two things that go together pretty well, all things considered Now You See Me combines the showy world of magicians with the twisty world of the con artist, These two discrete forms of professional liars have been paired many times throughout cinema history, but the best iteration I have seen takes us as far from glossy summertime fare as it is possible to go.

if you believe there's nothing up my sleeve, then nothing is cool - petri dish
This is one of those synchronicities between teaching and the information circulating around the web that I love so much. Jump-started by viewing R.E.M.’s video of their song "Man on the Moon" in class, we were talking about how the images of Newton and Darwin in the lyrics might resonate with questions of skepticism, of being kept off balance about judging whether something you are witnessing is real or not, about questions of evidence in coming to know the truth, and how one responds to others who question that truth. We spent a fair amount of time looking at the...
