Great post about work we have been doing at +Kitware to bring Google's Project Tango data into ParaView, and offer an open source tool to visualize all of the data those devices produce. I still haven't seen one of these devices, but very interesting developments in embedded 3D sensors!

Great to see this letter from the +National Science Foundation to explore norms and practices for software and data citation and attribution. Very important, I am very interested in this, and hope to see things improve as the value of software/data is recognized.

Something also explored in the WSSSPE workshop last year (http://wssspe.researchcomputing.org.uk/) with many interesting papers and a summary article currently being drafted. Exciting times as science opens up more, and software/data become more prominent as research products.

"Science requires openness to flourish," said Neil deGrasse Tyson on +COSMOSonTV.

It was so nice to hear #OpenScience  plugged on  #Cosmos  that we put together this commemorative graphic. cc +Neil deGrasse Tyson Fan Club

A nice explanation of the scientific method, although I am afraid most peer review does not live up to the extent asserted here. Many people are working on improving that situation too.
 
It amazes how many people don't understand this.
        Science is a process guided by simple set of rules scientists follow to make sure that what they do actually works. We have learned over the past four centuries that these are the bare minimum common sense rules to follow. Anything less and you will make mistakes and mislead people into believing falsehoods. Cold hard experience has taught us this over the generations.
        Too many people believe science is like some kind of religion, where people just hypothesize and decide that their hypotheses are true, and believe in these hypotheses dogmatically. Evolution and climate change have been specifically targeted by politicians who want people to believe this about science, and all of science suffers as a result of this misinformation. All of science suffers when more and more people misunderstand what it is.

Quote:
1. Make an Observation -- "What is happening?"
        An Observation is when you notice something in the world around you and decide you want to find out more about it.
2. Define the Question -- "Why is this happening?"
        Defining the question creates an idea that can be tested using a series of Experiments.
3. Form a Hypothesis -- "I think this happens because..."
        A Hypothesis is a statement that uses a few Observations, without any experimental evidence, to define why something happens.
4. Perform Experiments -- "Let's test my Hypothesis..."
        An Experiment is a series of tests to see if your Hypothesis is correct or incorrect. For each test, record the data you discover.
5. Analyze the Data -- "Was my Hypothesis right?"
        Analyzing data takes what you found in your Experiments and compares it to your Hypothesis. If needed, perform another Experiment to gather better data.
6. Conclusion -- "Experiments show my Hypothesis was..."
        Forming a Conclusion presents the Experimental Data and explains how it supports or rejects the Hypothesis. Often, Scientists will take this Conclusion and perform other Experiments on it to discover new things.

(end quote)

7. Request Peer Review -- "Did you get the same answer as me?"
        Ask other scientists to perform the same Experiments you did to check your work and make sure you didn't make mistakes, see if they come to the same Conclusion as you did. The more people who get the same answers as you, the more confidence everyone has that you are right.

Read all this year's GPU technology conference, which featured a great mixture of open source, Linux in several flavours (embedded, grid, super), gaming, virtual reality and rendering. There was also a good amount of science presented, using GPUs to accelerate simulations/calculations.

Congratulations to all of the community award winners, including +Luis Ibanez who introduced me to +Opensource.com. I also got a conversation starter award (does that mean I talk too much?)

Value for money???
 
"Higher priced titles do have higher Impact Factors and Eigenfactors, but the increase in the metrics is small when compared to the increase in costs, since the average price ($5,188) for the most expensive journals was 30 times higher than the average price ($158) for the least expensive journals. The increase in prices for the lower cost titles was lower than for the more expensive titles. Article Influence Score did not show a strong correlation between higher scores and prices...."

Nice video using #Lego  to explain #opensource  in everyday terms, along with simple examples of how everything is not free/gratis. It will take a while to change things, but hopefully videos like this can bring it home for more people.

Story
Tagline
Physicist, chemist, scientific visualization technical leader at Kitware.
Introduction
I work at Kitware, where my job involves developing open source, cross platform scientific visualization, pre and post processing code (mainly in C++, OpenGL, Qt) for scientific visualization. Strong believer in open science, open data and open source and proud member of Blue Obelisk. Everything posted is my opinion (may or may not coincide with my company, significant other, animal guide, etc).

I work on Open Chemistry software, such as Avogadro as well as other open source toolkits and applications VTK, ParaView, CMakeKDE and several other open source projects. My Ph.D. and degree are both in physics, with a large component of materials engineering. Working hard to improve the quality and openness of open source scientific software, specifically chemistry related software such as Avogadro and 2D charting/plotting in VTK.

Favourite quotations:

"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." Albert Einstein.

“I believe the simplest explanation is, there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization that there probably is no heaven and no afterlife either. We have this one life to appreciate the grand design of the universe and for that, I am extremely grateful.” Stephen Hawking.

Nice place, great beer, can be really tough actually tasting any on a weekend due to how busy they get.
