A British Teenager Has Corrected a Mistake in NASA’s Data


Kids these days…

 A British school student recently contacted NASA to point out that there was an error in data recorded on the International Space Station (ISS), earning him thanks from the US space agency.

Miles Soloman, a 17-year-old student from Tapton School in Sheffield, was working on the TimPix project, which lets school students in the UK access data recorded by radiation detectors during British astronaut Tim Peake’s six-month stay on the ISS.

 

Amongst other projects, Peake participated in a research program that aims to understand the impact of space radiation on humans. Radiation on the ISS is monitored with USB-shaped Timepix detectors, which are plugged into computers and regularly send data back to Earth.

Soloman and his fellow students were given these Timepix measurements in a giant pile of Excel spreadsheets, allowing them to practice data analysis on real-world scientific information.

When they sorted the data by energy levels, Soloman noticed something odd.

“I went straight to the bottom of the list, and went to the lowest bits of energy there were,” he told BBC Radio 4’s World at One current affairs program.

“I noticed that where we should have no energy, where there was no radiation, it was actually showing -1. The first thing I thought was ‘Well you can’t have negative energy,’ and then we realised that this was an error.”

Soloman and his physics teacher James O’Neill jumped into action and emailed NASA straight away.

 As Soloman explained to BBC Radio, researchers at NASA responded that they were aware of the error, but thought it had only been happening once or twice a year. They were wrong.

“What we actually found was that they were happening multiple times a day,” says Soloman.

“They thought they had corrected for this,” said physicist Lawrence Pinsky from the University of Houston, who is involved with the TimPix project, and is a collaborator of the radiation monitoring project on ISS.

“The problem is that some of the algorithms which converted the raw data were slightly off, and therefore when they did the conversion, they wound up with a negative number.”

Prompted by BBC’s World at One host Martha Kearney on whether such a revelation by a schoolboy was embarrassing, Pinsky answered that he didn’t think so.

“It was appreciated more so than being embarrassing,” he said. “The idea that students get involved at a real level means that there’s an opportunity for them to find things like this.”

The TimPix project is one of many initiatives organised by IRIS (the Institute for Research in Schools), a UK-based charitable trust that gives students and teachers opportunities to do actual scientific research at school.

IRIS has partnered with organisations such as CERN, NASA, Wellcome Trust, and the UK Royal Horticultural Society to bring real science projects into the classroom and get kids excited about pursuing careers in science.

“We’re also tapping into the potential of young minds and what they can do,” said Soloman’s teacher O’Neill. “As far as I’m concerned, the greatest research group we can form is our students around the country.”

Apart from analysing radiation exposure on ISS, students have also been doing genetic research into cardiovascular disease, analysing the atmosphere of Mars, and taking part in the MoEDAL experiment at the Large Hadron Collider, looking for signs of a magnetic monopole.

There’s even a project in the works that will let kids build a replica of the Large Hadron Collider in Minecraft, working in collaboration with the particle physics team from the University of Oxford.

At least for Miles Soloman, IRIS has definitely given him inspiration to pursue more science, although he hastens to explain that he wasn’t trying to outsmart NASA researchers when he pointed out the data error.

“I’m not trying to prove NASA wrong, I’m not trying to say I’m better, because obviously I’m not – they’re NASA,” he said. “I want to work with them and learn from them.”

Google Patents for contact lens that can scan your Iris


Google’s love for contact lenses is never ending. The search engine giant has already done considerable work on contact lenses and their use in health applications.

Now, Google has patented a new technology that transforms contact lenses into an identification device.

This new technology involves covering all parts of the iris of an eye. The contact lens surface contains one or more light sensors that are embedded on its surface and these reflect off light from the iris.

These sensors collect an image of the iris and it is then compared with the image of same iris saved in computer’s memory. If a match between the two images is found then a door for the wearer will be unlocked or else a file containing sensitive information might become accessible.

Specifications about the technology’s applications haven’t been disclosed in the patent. Presumably, the lenses will be used for biometric authentications in numerous contexts.

Google has been testing smart contact lenses, which can be used one day by diabetics for measuring their blood sugar levels. In such type of lens, a small chip along with sensors is embedded between two coats of lens material. Tears touch the sensors through a small perforation in the material of the lens and thus, the sensors acquire blood sugar levels form the liquid. Through this lens, blood sugar level can be tested once every second.
