First Picture of Black Hole

April 12th, 2019 No comments
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of the supermassive black hole in the centre of Messier 87 and its shadow. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon. Although the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks — hydrogen masers — which precisely time their observations. These observations were collected at a wavelength of 1.3 mm during a 2017 global campaign. Each telescope of the EHT produced enormous amounts of data – roughly 350 terabytes per day – which was stored on high-performance helium-filled hard drives. These data were flown to highly specialised supercomputers — known as correlators — at the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory to be combined. They were then painstakingly converted into an image using novel computational tools developed by the collaboration.

And here is a TED video on how it was done…..

STEM Instruction: How Much There Is and Who Gets It

February 5th, 2019 No comments

From: http://blogs.edweek.org/edweek/curriculum/2019/01/survey_gives_new_insights_into.html

Despite a push for greater STEM instruction, students and teachers continue to experience inequitable access to STEM-related classes and resources, according to a new survey of 1,200 schools and 7,600 teachers.

This nationally representative study is the sixth in a series of surveys on K-12 STEM education and college and career readiness dating back to 1977, but the first to put an emphasis on computer science and engineering. The survey, conducted by Horizon Reasearch, Inc. and commissioned by the National Science Foundation, covered a variety of topics relevant to teachers, giving insights into instructional practices, course offerings, resources, and professional development participation in K-12 math, science, and computer science.

What is Pocket Science Lab

All in One Device. PSLab is a small USB powered hardware extension for your Android phone or PC that lets you measure all kinds of things. PSLab comes with a built-in Oscilloscope, Multimeter, Wave Generator, Logic Analyzer, Power Source, and we are constantly adding more digital instruments. PSLab is many devices in one. Simply connect two wires to the relevant pins and start measuring. You can use our Open Source Android or desktop apps to view and collect the data. You can also plug in hundreds of compatible I2C standard sensors to the PSLab pin slots. It works without the need for programming. So, what experiments you do is just limited to your imagination! PSLab is developed by FOSSASIA and OpnTec in collaboration with a global community of Open Source developers.

Amazon To Make Its Engineering Training Courses Available For Free.

December 21st, 2018 No comments

TechCrunch (11/26, Loizos) reports that AWS announced Monday “it has made available, for free, the same machine learning courses that it uses to train its own engineers.” Paraphrasing Amazon GM of AI and Deep Learning Dr. Matt Wood, TechCrunch says “there are more than 45 hours across 30 different courses that developers, data scientists, data platform engineers, and business professionals can take gratis.” Wood said each lesson “starts with the fundamentals, and builds on those through real-world examples and labs, allowing developers to explore machine learning through some fun problems we have had to solve at Amazon.” According to TechCrunch, the company “is also introducing its own machine-learning certification that customers can take right now for half price.” TechCrunch says, “Presumably, part of the idea is to enhance Amazon’s retail pages, as well to potentially to recruit more people into the company so it can accelerate its own growth. If Amazon earns some much needed goodwill along the way, so be it.”

Robotics engineer Barbie joins the girls who code

LOS ANGELES (Reuters) – Barbie, the world’s most iconic doll, is venturing into coding skills in her latest career as a robotics engineer.

The new doll, launched on Tuesday, aims to encourage girls as young as seven to learn real coding skills, thanks to a partnership with the kids game-based computing platform Tynker, toymaker Mattel said.

Robotics engineer Barbie, dressed in jeans, a graphic T-shirt, denim jacket and wearing safety glasses, comes with six free Barbie-inspired coding lessons designed to teach logic, problem solving and the building blocks of coding.

The lessons show girls, for example, how to build robots, get them to move at a dance party, or do jumping jacks.

According to U.S. Department of Commerce statistics, only 24 percent of STEM (Science, Technology, Engineering, Math) jobs were held by women in 2017.

Barbie has held more than 200 careers in her almost 60-year life, including president, video game developer and astronaut.

Tynker co-funder Krishna Vedati said in a statement that the company’s mission to empower youth worldwide made Barbie an ideal partner “to help us introduce programming to a large number of kids in a fun engaging way.”

Tennessee Coding School Training Young Adults As Software Engineers.

August 19th, 2018 No comments

The Memphis (TN) Commercial Appeal (8/4, Lopez) reports Code Crew Code School in Memphis, Tennessee “is training 16 young adults to become entry-level software engineers, earning $60,000 a year, for free.” The paper says that four years of training are condensed into a “six-month coding boot camp.” The school “launched three years ago, teaching after-school programs, summer camps, in-school electives and pop-up classes. The group focused on teaching elementary, middle and high school-aged children computer science.”
