Další kurzy na Khan Academy - Programování

Dobrý den,

ikdyž se to většiny z vás nemusí týkat, mě to opět vyrazilo dech a beru to jako další skvělou aktivitu Khan Academy. Pokud někdo chce začít s programováním, Khan mu může dát skvělou představu co to obnáší a pevné základy pro další kurzy např. v CTY programech.

Computer programming changed my life. I first programmed games on my graphing calculator as a hobby in 9th grade. That hobby turned into stimulating internships later in high school. That helped me get into and succeed in college. When I graduated in the late 90s, the ability to code that I had honed since high school became one of the key gateways to a rewarding profession. Even Khan Academy wouldn’t exist if I hadn’t been able to write the software in 2005 to make it all work!

Fast forward to 2014, and the importance of coding has only accelerated. Regardless of what career a student chooses, the ability to design and understand software will be be invaluable.

Start the Hour of Code

The Hour of Code is an hour-long introduction to computer programming designed to demystify coding and show students that everyone can learn the basics. At Khan Academy, we’ve crafted several custom-made tutorials for your students that require no prior experience.

Hour of Drawing with Code: Students will learn to program using JavaScript, one of the world's most popular programming languages via two great options:

• Drag-and-drop: experimental block-based coding for younger students with less-developed typing skills and students on tablet devices (ages 8+).
• Typing: keyboard-based coding for older students (ages 10+).

Hour of Webpages: Students will learn to make their own webpages using the basics of HTML and CSS (ages 10+).

Hour of Databases: Students will learn the fundamentals of databases using SQL to create tables, insert data into them, and do basic querying (ages 12+).

Last year, 15 million students tried computer programming for at least one hour during Computer Science Education Week on Khan Academy and other platforms.

This year, our goal is to reach 100 million students.

I can’t wait to see what everyone makes!

Sal
Founder of Khan Academy and lover of code

Zkuste najít Higgsův boson - Oxford

Join the hunt to break the Higgs boson 'barrier'

SCIENCE

Online volunteers are being asked to spot tiny explosions that could be evidence for new particles that will require new models of physics.

Higgs Hunters [www.higgshunters.org], a project launched today by UK and US scientists working on the ATLAS experiment, enables members of the public to view 25,000 images recorded at CERN’s Large Hadron Collider. By tagging the origins of tracks on these images volunteers could spot tiny sub-atomic explosions caused when a Higgs boson 'dies', which some scientists think could generate a kind of particle new to physics.

'If anything discovering what happens when a Higgs boson 'dies' could be even more exciting than the original discovery that the Higgs boson exists made at CERN back in 2012,' said Professor Alan Barr of Oxford University's Department of Physics, lead scientist of the Higgs Hunters project. 'We want volunteers to help us go beyond the Higgs boson 'barrier' by examining pictures of these collisions and telling us what they see.'

In the ATLAS experiment at CERN's Large Hadron Collider protons are smashed together at up to one billion kilometres per hour. Such collisions can generate Higgs bosons: these are known to rapidly decay into other particles and some scientists believe these could include a new type of previously unobserved particle. Simulations predict that these new particles should leave tell-tale tracks inside the ATLAS experiment, which computer programs find difficult to identify, but which human eyes can often pick out.

Professor Andy Haas of New York University said: 'Writing computer algorithms to identify these particles is tough, so we're excited to see how much better we can do when people help us with the hunt.'

Professor Chris Lintott of Oxford University's Department of Physics, Zooniverse Principal Investigator, said: 'The most exciting citizen science comes when you find the unexpected lurking amongst the data, and who knows what could be out there in the data from the ATLAS experiment?'

Professor Dave Charlton, spokesperson of the ATLAS Collaboration, said: 'With the Higgs Hunters project, people can look directly at ATLAS data to help us find unexpected phenomena - perhaps volunteers will be able to spot new physics with their own eyes!'

A successful detection of new particles would be a huge leap forward for particle physics, as they would lie beyond the Standard Model – the current best theory of the fundamental constituents of the Universe.

The Higgs Hunters project is a collaboration between scientists at the University of Oxford, New York University, the University of Birmingham, the Zooniverse project, and the ATLAS experiment at CERN. The project was funded by a Google Global Impact Award, by the UK's Science & Technology Facilities Council, and by the US National Science Foundation.
