[WSG20] Study Group to Meet Daily in the Month of April

Wolfram Study Groups (WSG) are a new special program, set up to be fun, directed and incremental online learning resources. There is something for everyone, whether you are a student, an educator/parent looking for quality resources, or an adult interested in learning new skills. The group that is getting started now offers a daily opportunity to meet online with others interested in building Wolfram Language skills. Each session will include short lesson videos from the interactive course An Elementary Introduction to the Wolfram Language, based on Stephen Wolfram’s book, with experts on hand to explain concepts in more depth. We plan to include multiparadigm data science and other application topics too. Sessions run Monday through Friday, 12-1pm US EDT (4-5pm GMT). A certificate of program completion will be awarded to participants who attend online sessions and pass auto-graded online quizzes. Sign up and receive email reminders of upcoming sessions, or join a session in progress.

Great series. I completed the four quizzes. Do we need to do anything else to request a certificate?

POSTED BY: Abrita Chakravarty

New Study Group dates have been added for May! This new Study Group begins Monday, May 4, and will go beyond beginner-level topics and cover practical programming, working with data, building simple interfaces, expressions, assignments, patterns, user-defined functions and package development. Earn a certificate of program completion through attendance and quizzes. Wolfram Technology Certified Level I will be awarded to participants who successfully complete assigned problems.

like this code(Graphics3D[ Table[Style[Sphere[RandomInteger[10, 3]], Opacity[0.5]], 100]]) but i want the same volume of above Parallelepiped and i want to change number of atoms with time to be every one minute one atom and after 240 minutes the Parallelepiped will be full of 240 atoms
POSTED BY: M al

May be this is what you want:

h = 10;
l = 6;
w = 4;
r = 0.2;
atoms = Table[
   Sphere[{RandomReal[w - r], RandomReal[l - r], RandomReal[h - r]}, 
    r], 240];
Manipulate[
 Graphics3D[{Opacity[0.2], 
   Parallelepiped[{0, 0, 0}, {{w, 0, 0}, {0, l, 0}, {0, 0, h}}], 
   Opacity[0.5], Red, atoms[[1 ;; n]]}, Axes -> True, 
  AxesStyle -> GrayLevel[0], ViewPoint -> {1.3, -2.4, 2.}], {n, 0, 
  240, 1}]

i create this code (Show[Graphics3D[ Parallelepiped[{0, 0, 0}, {{10, 0, 0}, {0, 6, 0}, {0, 0, 4}}], {Axes -> True, AxesStyle -> GrayLevel[0]}], ViewPoint -> {1.3, -2.4, 2.}]), How can i put an atom every one mint and after 240 mints the parallepiped will be full of atoms.
POSTED BY: M al

Do you mean something like the following?

h = 10;
l = 6;
w = 4;
r = 0.2;
Graphics3D[{Opacity[0.2], 
  Parallelepiped[{0, 0, 0}, {{w, 0, 0}, {0, l, 0}, {0, 0, h}}], 
  Opacity[0.5], Red, 
  Table[Sphere[{RandomReal[w - r], RandomReal[l - r], 
     RandomReal[h - r]}, r], 240]}, Axes -> True, 
 AxesStyle -> GrayLevel[0], ViewPoint -> {1.3, -2.4, 2.}]

Hello Abrita, Excellent , Thank you very much. Just tried it and it works like a charm. I will compare the 2 commands and see how you modified them. Andrew

For your second question: you may want to look at http://reference.wolfram.com/language/ref/ChromaticityPlot.html
POSTED BY: Abrita Chakravarty

Perfect and thanks very much! Andrew
POSTED BY: Andrew Skipor

For your first question you want to modify the code as follows:

Import["https://images.search.yahoo.com/search/images;_ylt=AwrExo6gMpdei08AnAmLuLkF;_ylc=X1MDOTYwNTc0ODMEX3IDMgRmcgMEZ3ByaWQDMkFybVJzZFBSbmVtRGs0aHVwdU1oQQRuX3N1Z2cDMTAEb3JpZ2luA2ltYWdlcy5zZWFyY2gueWFob28uY29tBHBvcwMwBHBxc3RyAwRwcXN0cmwDBHFzdHJsAzQEcXVlcnkDbGlseQR0X3N0bXADMTU4Njk2NzIwNQ--?fr2=sb-top-images.search&p=lily&ei=UTF-8&iscqry=&fr=sfp","Images"]

To look for images at a URL, use the "Images" option with Import:

Import[<URL>,"Images"]
POSTED BY: Abrita Chakravarty

I do have 2 questions, I tried doing get data from the internet like "lily" the flower, but it was a mess: here is the example tried.How does one actually get images of the flower "lily"as an example.

Import["<a href="https://images.search.yahoo.com/search/images;https://images.search.yahoo.com/search/images;ylt=\ A0geKLottpVe0NMA0RRXNyoA;_ylu=\ X3oDMTE0cTZhamZ0BGNvbG8DYmYxBHBvcwMxBHZ0aWQDQTA2MjJfMQRzZWMDcGl2cw--?\ p=lily&fr2=piv-web&fr=mcafee"]

My other question is there a command to to get the color coordinate function. Looking to get this plot I do have 2 questions, I tried doing get data from the internet like "lily" the flower, but it was a mess: here is the example tried.How does one actually get images of the flower "lily"as an example.

Import["<a href="https://images.search.yahoo.com/search/images;https://images.search.yahoo.com/search/images;ylt=\ A0geKLottpVe0NMA0RRXNyoA;_ylu=\ X3oDMTE0cTZhamZ0BGNvbG8DYmYxBHBvcwMxBHZ0aWQDQTA2MjJfMQRzZWMDcGl2cw--?\ p=lily&fr2=piv-web&fr=mcafee"]

Correct, no Study Group today. Instead, we encourage everyone to attend the New in Wolfram Language 12.1 webinar, starting at 12pm US EDT (5pm GMT) today. Jon McLoone will share an engaging overview presentation with us, and we'll dive into specific topics in detail at upcoming Wednesday webinars. Join by logging in here: https://wolfr.am/LOBWol90
