A group of students at Aalborg University are building DIY satellites for maritime traffic monitoring - and for fun!
This brief timelapse shows the assembly of their 4th model AAUSAT4. Another model, AAUSAT5, is also under construction and will be launched from the ISS in October 2015.
I don't think I had the opportunity to participate in such a cool project at the time I studied...

Yes, giraffes are cute, but no, that shouldn't give them special protection not offered to other animals.
Playing with virtual LEGO is not quite the same as the real thing and it's frustrating to be limited to so few pieces. Still, the Chrome/Maps/LEGO thingy is pretty fun to toy around with for awhile.
This also reminded me of this fantastic commercial for a limited-edition wooden Docomo/Sharp smartphone from 2011:
I therefore set out to make some milk and it turned out to be quite an enjoyable process - and the result was great!
When searching for recipes, you'll find many different ways of doing it, but they mostly involve soaking, blending, straining and boiling the beans. The one I followed was this very detailed one with nice photos:
To summarize the process, these were the steps I took:
1. Soak 2 dl (160 g) of beans overnight (10-12 hours) - they will more than double in volume.
2. Remove shells by placing in fresh water and rubbing the beans between your finger tips - this was the most time-consuming step and apparently not absolutely necessary.
3. Blend the beans with water in batches for 3-5 minutes, 1 part beans to 2 parts water (by volume). I had 5 dl of beans and 1 l of water in two batches.
4. Strain the liquid into a pot through a cheese/muslin cloth placed on a sieve.
5. After straining for a few minutes, gather the cloth around the remaining mass and press and twist until all the liquid has been squeezed out. The remaining ground meal (okara) has a boring taste but great texture - we used it for delicious burger paddies together with minced beef (around 1:2).
6. Bring all the milk to a boil and simmer for 20 minutes. It almost boiled over at one point when I had briefly left the kitchen, so pay attention!
7. You can add salt, sugar or flavouring to the milk when boiling. As this was intended for tofu, I kept it plain.
8. Skim off the skin on top and cool down the milk.

Yesterday’s post about the big bang and cosmic origins struck a few nerves. Responses ranged from vulgar insults to dismissals of the post as “just a theory.” But more subtle were the criticisms that declared the post lacked humility. Scientific knowledge is never perfect, and to claim the validity of the big bang is to go too far. When communicating to the general public scientists should never say “we know”, only that “we might know.” Scientists should show more humility.
Such criticism fails to recognize that the power of science is its humility. In fact, the scientific process is based on the assumption that individual scientists won’t easily show humility on their own, so it is imposed upon them. There are three basic tenets of scientific research: it must be based upon verifiable data, it must be done publicly, and it must be open to criticism.
Most people view scientific evidence as repeatable experiments that can be done in the lab. For this reason the findings of evolution or cosmology are often countered with “you weren’t there.” But verifiable data is much broader than simply lab experiments. It is a process of gathering data that clearly documents when, where and how the data was gathered. If you gather observational data, the burden is on you to document its origin. If you use data gathered by others, you must clearly cite your sources.
Once you have your observational results or theoretical work, the next step is to present it publicly. This could be a conference, a preprint archive, a book, or submission to a research journal. A scientific discovery is meaningless if it isn’t disseminated. Publication provides a record of the work, so it can’t be tossed down the memory hole. Make a significant discovery, and the record is there. Make a foolish claim, and that’s there too. It’s the latter possibility that strikes fear into scientists everywhere, because publishing your work isn’t sufficient. When you make your research public your colleagues now have a chance to pull the work apart and see if it really says what you think it says. It gets subjected to peer review.
Peer review can be the most frustrating and most humiliating aspect of scientific research. That’s why it’s considered the gold standard of science. Having research published in a peer-reviewed journal means that the work has been examined by other experts in your field, and has been found clear and without obvious error. It doesn’t mean its perfect, but it does mean the work has been held to a high standard and survived. This is why when I write about new scientific work I focus on peer reviewed articles. When I write about work that hasn’t been peer reviewed, I clearly say so.
Of course even after conducting your research, organizing your results, checking it with friendly colleagues, presenting it publicly and submitting it to peer review, you still aren’t done. You’re never done, because at any time someone can critically review your work again. If you have a great theory and your predictions don’t support new findings, we look for something better. No matter how famous, or how many awards you may have, anyone can be toppled by new scientific discovery.
That’s the deal. Keep pushing back against ideas. Keep working to develop better theories. Always, always keep in mind that your theories might just be wrong.
What survives is an understanding of the universe that it robust. It is a confluence of evidence that supports a deep theoretical framework. It is knowledge humbly gathered, and put forward with humility. Through a process that recognizes human fallibility. It is humanity’s best understanding of what is real and true about the cosmos.
This is why I present ideas like the big bang with the claim that we know. We Know. We know because thousands of individuals have devoted their lives to understanding the universe. Devoted their lives to getting it right. Relying on a process that forces us to be humble, and forces us to defend our ideas over and over.
In my posts I always strive to present our best understanding of the universe in a way that is clear and meaningful. That’s why I try to limit moderation of the comments. It is a kind of peer review. I write about science to the best of my ability, and everyone is free to criticize it. I’ve made mistakes in my posts and been called on them. I’ve been praised and thanked for making things clear. I’ve also been called a liar. A fool. Prideful. Deceitful. Ignorant. Arrogant.
Fair enough. That’s the deal.

Buttered Cat Paradox
The buttered cat paradox is a common joke based on the tongue-in-cheek combination of two adages:
• Cats always land on their feet.
• Buttered toast always lands buttered side down.
The paradox arises when one considers what would happen if one attached a piece of buttered toast (butter side up) to the back of a cat, then dropped the cat from a large height. Some people jokingly maintain that the experiment will produce an anti-gravity effect. The faux paradox has captured the imagination of science-oriented humorists.
The idea appeared on the British panel game QI, where the idea was discussed. As well as talking about the idea, they also brought up other questions regarding the paradox. These included "Would it still work if you used margarine?", "Would it still work if you used I Can't Believe It's Not Butter?", and "What if the toast was covered in something that was not butter, but the cat thought it was butter?", the idea being that it would act like a placebo. The paradox also appeared in the episode "Gravitational Anarchy" of the scientific podcast RadioLab.
Brazilian energy drink brand Flying Horse has released a commercial that simulates the recreation of this phenomenon, which is then used to create perpetual energy. I used the commercial to make the gif. below.
Oi, oi, oi - The LEGO Movie seems to be better than one could possibly have hoped for. Gotta check the cinema schedules!
100% so far on Rotten Tomatoes (although it's still early):
Good tofu is pretty hard to come by in Copenhagen, so for a while we have wanted to try to make our own. After having made a delicious, rich soy milk from scratch (http://goo.gl/Hw54u2), making the tofu was easy. Our rice cooker has a "tofu" program, so after mixing 4 dl of the soy milk with 5 ml of liquid nigari¹, it was a simple press on a button and 50 minutes wait.
The result was a delicious, creamy tofu with a subtle bean flavour and smooth texture. Because of the limited amount and because of its pudding-like wobbliness we couldn't cut it into nice, big blocks. Therefore the presentation here may not look very appetizing - perhaps also due the toning of the photo - but trust me, it was yummy!
The topping is mentsuyu (could have been just soy sauce), grated
gringer and pickled nameko mushrooms.
¹ Nigari is magnesium chloride (with traces of other minerals) used either as a powder or liquid for coagulating the soy milk. Gypsum can apparently be used instead.

And yes, I completely forgot about the katsuobushi - that's of course perfect as well. I think two different toppings apart from the shoyu is a pretty good balance of minimalism and interesting taste.
, enjoy! Now I'm starting to think about what I should prod my wife for... :)
The dataset from 2004 is from the Reality Mining project at MIT which tracked the interactions between around 100 students and faculty members via data from their mobile phones.
A new project at the Technical University of Denmark, SensibleDTU, will be carrying out a similar experiment on a larger scale: 1000 new students will be offered a Nexus 4 phone which will track their interactions in much higher detail than in the Reality Mining project (of course made possible by 10 years of technological advances).
The outcome of this new research project will hopefully be more easily accessible.
