Rap hip-hop and physics

A Hip-Hop Experiment


Only 4 percent of African-American seniors nationally were proficient in sciences, compared with 27 percent of whites, according to the 2009 National Assessment of Educational Progress.

GZA by bringing science into hip-hop; Dr. Emdin by bringing hip-hop into the science classroom.

the popular hip-hop lyrics Web siteRap Genius, will announce a pilot project to use hip-hop to teach science in 10 New York City public schools. The pilot is small, but its architects’ goals are not modest. Dr. Emdin, who has written a book called “Urban Science Education for the Hip-Hop Generation,”

hip-hop “cypher,” participants stand in a circle and take turns rapping, often supporting or playing off one another’s rhymes.

“All of those things that are happening in the hip-hop cypher are what should happen in an ideal classroom.”

Fifteen states now require all high schools to offer computer science courses. Twenty-three states have created K-12 computer science standards. And 40 states plus the District of Columbia allow students to count computer science courses toward high school math or science graduation requirements. That’s up from 12 states in 2013, when launched, aiming to expand access to computer science in U.S. schools and increase participation among girls and underrepresented minorities in particular.

Nevada is the only state so far to embed math, science, English language arts and social studies into its computer science standards.

coding ethics unpredictability

Franken-algorithms: the deadly consequences of unpredictable code

by  Thu 30 Aug 2018

Between the “dumb” fixed algorithms and true AI lies the problematic halfway house we’ve already entered with scarcely a thought and almost no debate, much less agreement as to aims, ethics, safety, best practice. If the algorithms around us are not yet intelligent, meaning able to independently say “that calculation/course of action doesn’t look right: I’ll do it again”, they are nonetheless starting to learn from their environments. And once an algorithm is learning, we no longer know to any degree of certainty what its rules and parameters are. At which point we can’t be certain of how it will interact with other algorithms, the physical world, or us. Where the “dumb” fixed algorithms – complex, opaque and inured to real time monitoring as they can be – are in principle predictable and interrogable, these ones are not. After a time in the wild, we no longer know what they are: they have the potential to become erratic. We might be tempted to call these “frankenalgos” – though Mary Shelley couldn’t have made this up.

Twenty years ago, George Dyson anticipated much of what is happening today in his classic book Darwin Among the Machines. The problem, he tells me, is that we’re building systems that are beyond our intellectual means to control. We believe that if a system is deterministic (acting according to fixed rules, this being the definition of an algorithm) it is predictable – and that what is predictable can be controlled. Both assumptions turn out to be wrong.“It’s proceeding on its own, in little bits and pieces,” he says. “What I was obsessed with 20 years ago that has completely taken over the world today are multicellular, metazoan digital organisms, the same way we see in biology, where you have all these pieces of code running on people’s iPhones, and collectively it acts like one multicellular organism.“There’s this old law called Ashby’s law that says a control system has to be as complex as the system it’s controlling, and we’re running into that at full speed now, with this huge push to build self-driving cars where the software has to have a complete model of everything, and almost by definition we’re not going to understand it. Because any model that we understand is gonna do the thing like run into a fire truck ’cause we forgot to put in the fire truck.”

Walsh believes this makes it more, not less, important that the public learn about programming, because the more alienated we become from it, the more it seems like magic beyond our ability to affect. When shown the definition of “algorithm” given earlier in this piece, he found it incomplete, commenting: “I would suggest the problem is that algorithm now means any large, complex decision making software system and the larger environment in which it is embedded, which makes them even more unpredictable.” A chilling thought indeed. Accordingly, he believes ethics to be the new frontier in tech, foreseeing “a golden age for philosophy” – a view with which Eugene Spafford of Purdue University, a cybersecurity expert, concurs. Where there are choices to be made, that’s where ethics comes in.

our existing system of tort law, which requires proof of intention or negligence, will need to be rethought. A dog is not held legally responsible for biting you; its owner might be, but only if the dog’s action is thought foreseeable.

model-based programming, in which machines do most of the coding work and are able to test as they go.

As we wait for a technological answer to the problem of soaring algorithmic entanglement, there are precautions we can take. Paul Wilmott, a British expert in quantitative analysis and vocal critic of high frequency trading on the stock market, wryly suggests “learning to shoot, make jam and knit

The venerable Association for Computing Machinery has updated its code of ethics along the lines of medicine’s Hippocratic oath, to instruct computing professionals to do no harm and consider the wider impacts of their work.

income-share agreements (ISAs)

income-share agreements (ISAs)

A new way to get people into coding

Want to learn to code without paying up front? Programs such as Lambda School, App Academy and even Purdue University are experimenting with income-share agreements (ISAs), in which students agree to pay a portion of their income after graduation, reports The Atlantic. It’s a promising idea, particularly when businesses needs to fill over half a million computer-science jobs. But the schemes are still in their infancy, and it remains to be seen whether ISAs prove to be a viable business model or successful for graduates.

In computingReact (sometimes styled React.js or ReactJS) is a JavaScript library[2] for building user interfaces.

It is maintained by FacebookInstagram and a community of individual developers and corporations.[3][4][5]

React allows developers to create large web-applications that use data and can change over time without reloading the page. It aims primarily to provide speed, simplicity, and scalability. React processes only user interfaces in applications. This corresponds to View in the Model-View-Controller (MVC) pattern, and can be used in combination with other JavaScript libraries or frameworks in MVC, such as AngularJS.[6]

Software Carpentry Workshop

Minnesota State University Moorhead – Software Carpentry Workshop

Reservation code: 680510823  Reservation for: Plamen Miltenoff

Hagen Hall – 600 11th St S – Room 207 – Moorhead



Jeff – certified Bash Python, John

what is shall and what does it do. language close to computers, fast.

what is “bash” . cd, ls

shell job is a translator between the binory code, the middle name. several types of shells, with slight differences. one natively installed on MAC and Unix. born-again shell

bash commands: cd change director, ls – list; ls -F if it does not work: man ls (manual for LS); colon lower left corner tells you can scrool; q for escape; ls -ltr

arguments is colloquially used with different names. options, flags, parameters

cd ..  – move up one directory .      pwd : see the content      cd data_shell/   – go down one directory

cd ~  – brings me al the way up .        $HOME (universally defined variable

the default behavior of cd is to bring to home directory.

the core shall commands accept the same shell commands (letters)

$ du -h .     gives me the size of the files. ctrl C to stop

$ clear . – clear the entire screen, scroll up to go back to previous command

man history $ history $! pwd (to go to pwd . $ history | grep history (piping)

$ cat (and the file name) – standard output

$ cat ../

how to edit and delete files

to create new folder: $ mkdir . – make directory

text editors – nano, vim (UNIX text editors) .      $ nano draft.txt .  ctrl O (save) ctr X (exit) .
$ vim . shift  esc (key)  and in command line – wq (write quit) or just “q”

$ mv draft.txt ../data . (move files)

to remove $ rm thesis/:     $ man rm

copy files       $cp    $ touch . (touches the file, creates if new)

remove $ rm .    anything PSEUDO is dangerous   Bash profile: cp -i

*- wild card, truncate       $ ls analyzed      (list of the analyized directory)

stackoverflow web site .


head command .  $head (check only the first several lines of a large file

$ for filename in basilisk.dat unicorn.dat . (making a loop = multiline)

> do (expecting an action) do

> head -n 3 $filename . (3 is for the first three line of the file to be displayed and -n is for the number)

> done

for doing repetitive functions


$ for filename in *.dat ; do head -n 3$x; done

$ for filename in *.dat ; do echo $filename do head -n 3$x; done

$ echo $filename (print statement)

how to loop

$ for filename in *.dat ; do echo $filename ; echo head -n 3 $filename ; done

ctrl c or apple comd dot to get out of the loop


$ for filename in *.dat

> do

> $filename

> head -n  10 (first ten files ) $filename | tail  -n 20 (last twenty lines)

$ for filename  in *.dat

>> echo  $filename
>> done

$ for filename in *.dat
>> do
>> cp $filename orig_$filename

history > something else

$ head something.else


another function: word count

$ wc *.pdb  (protein databank)

$ head cubane.pdb

if i don;t know how to read the outpun $ man wc

the difference between “*” and “?”

$ wc -l *.pdb


wc -l *.pdb > lenghts.txs

cat lenghts.txt

$ for fil in *.txt
>>> do
>>> wc -l $fil

by putting a $ sign use that not the actual text.


nano . The entire point of shell is to automate

$ bash (exectubale) to run the program

rwx – rwx – rwx . (owner – group -anybody)


$ file

$path .

$ echo $PATH | tr “:” “\n”








$ export PATH=$PWD:$PATH

(this is to make sure that the last version of Python is running)

$ ls ~ . (hidden files)        

$ ls -a ~

$ touch .bach_profile .bashrc

$history | grep PATH

   19   echo $PATH

   44  echo #PATH | tr “:” “\n”

   45   echo $PATH | tr “:” “\n”

   46   export PATH=$PWD:$PATH

   47  echo #PATH | tr “:” “\n”

   48   echo #PATH | tr “:” “\n”

   55  history | grep PATH


wc -l “$@” | sort -n ($@  – encompasses eerything. will process every single file in the list of files


$ chmod (make it executable)


$ find . -type d . (find only directories, recursively, ) 

$ find . -type f (files, instead of directories)

$ find . -name ‘*.txt’ . (find files by name, don’t forget single quotes)

$ wc -l $(find . -name ‘*.txt’)  – when searching among direcories on different level

$ find . -name ‘*.txt’ | xargs wc -l    –  same as above ; two ways to do one and the same

python is a 0 based language. starts counting with 0 – Java, C, P

atom_name = ‘helium ‘
print(atom_name[0])                  string slicing and indexing is tricky

atom_name = ‘helium ‘
atom_name = ‘helium ‘
print(atom_name[7])                python does not know how to slice it
synthax of python is        start : end : countby/step
string versus list .   string is in a single quote, list will have brakets
strings allow me to work not only w values, revers the string
atom_name = ‘helium lithium beryllium’
muillyreb muihtil muileh
Atom_name = ‘helium’
len (atom_name)                                     6 .             case sensitive
to clean the memory, restart the kernel
objects in Python have different types. adopt a class, value may have class inherent in its defintion
print (type(’42’)) .   Python tells me that it is a string
print (type(42)) .    tells e it is a string
to combine integer and letter: print (str(1) + ‘A’)
converting a string to integer . : print (1 + int(’55’)) .    all the same type
translation table. numerical representation of a string
print (‘half is’, 1 / 2.0)
built in functions and help
print is a function, lenght is a function (len); type, string, int, max, round,
Python does not explain well why the code breaks
ASCI character set – build in Python conversation
libraries – package:
function “import”

**For windows users only: set up git 
python is object oriented and i can define the objects
python creates its own types of objects (which we model) and those are called “DataFrame”
method applied it is an attribute to data that already exists. – difference from function . is function – it does not take any arguments
data.columns . is a method
print (data.T) .  transpose.  not easy in Excel, but very easy in Python
print (data.describe()) .
%matplotlib inline teling Jupyter notebook

import pandas

data = pandas.read_csv(‘/Users/plamen_local/Desktop/data/gapminder_gdp_oceania.csv’ , index_col=’country’)

GD plot 2 is the most well known library.

xelatex is a PDF engine.  reST restructured text like Markdown.  google what is the best PDF engine with Jupyter

four loops .  any computer language will have the concept of “for” loop. In Python: 1. whenever we create a “for” loop, that line must end with a single colon

2. indentation.  any “if” statement in the “for” loop, gets indented
