Guest post: Stereoscopy (The Illusion of Depth)

Hello there, and nice to meet you! I'm Cass, a British schoolgirl and wannabe scientist from my little corner of the blogosphere, Undercover Dress-Up Lover. Though faceless, I really am mostly harmless, except whilst practising violin or playing video games, when I make a lot of horrible noises you would probably rather not hear. While the lovely Annika is occupied with all the trials and tribulations of moving house, I'm going to do my best to provide you a crash course in stereoscopy, the illusion of depth. Grab a ruler and get in front of a mirror and measure how far apart your eyeballs are. Are you getting about 6 or 7cm between your pupils? This means each eye sees everything from slightly different angles to each other. Your brain is rather good at correlating these two images, one from each eye, to help you judge how far away things are from you. 3D films use stereoscopy - creating the illusion of depth - by simultaneously displaying two images which are polarised differently. The two lenses of the 3D glasses you wear are also polarised, so lets in one image into your left eye, and another into your right eye. What's polarisation? Visible light is a transverse wave, so it can be polarised. The particles in a polarised wave vibrate only in one plane. Below is an unpolarised wave on the left travelling right, going trough a polarising filter, and coming out polarised. So the light wave particles of one image of the film are vibrating in one certain direction, and one lens of the glasses only allow waves polarised in that plane through. This is also how those 'anaglyph' red and blue glasses work, except they filter by wavelength (different wavelengths are different colours) and aren't as good as polaroids because polaroids allow you to see the film in proper colour.

The skeletal element is interesting anyway, but if you buy this dress, you get free glasses too! From Fashionably Geek Why not utilise every glorious dimension of space through what you wear? Pompoms and ruffly flowers that stand out from the fabric are quirky and interesting embellishments that add a whole new texture to an outfit. Or, try something with a 2D stereoscopic print that looks 3D, with the use of anaglyph glasses or otherwise... || Chloe T. || Chai M. || Emma E. || || Joellen L. || Zoe Y. || Stephanie L. || I hope you all enjoyed guest-poster Cass' post about Stereoscopy, and learnt something new!

Ladybirds (Everywhere!) / A Call for Guest Bloggers / The Scientific Power of Thought

As I was racking my brains as to what to wear to Sydney rental inspections last week (notoriously one of the most difficult rental markets in the world), this awesome care-package from US Trendy with a Miss Patina dress inside arrived in the mail, along with these fantastic cat collar clips from Lady Bird Likes. (Funnily enough, the dress also had a lady bird print on it, which was a weird co-incidence as the collar clips are from an etsy shop with lady bird in their name!) And I have some really exciting news! The outfit must have worked a treat, because we were accepted for a really really (I mean, for the standards of a first-time-renting student) lovely property! So, for the next week or so, I'm going to be moving house! But I'm also going to university at the same time, and in between packing, it means I'm not actually going to have time to blog. I was wondering, if there were any super lovely bloggers out there who wanted to write guest posts for me, to be put up over the next week or two? I'm particularly looking for DIY, crafts, vintage style or science-themed posts (but am open to any other idea as well)! Shoot me an email at annikavictoria@gmail.com with your ideas first, if there's anyone out there who feels like helping me out! :] Also, if you can see them, please excuse my dodgy nail colour polish - I had my nails painted by a 6-year-old the other day and she was really proud of it (she actually did a pretty good job for a 6-year-old I think). dress - c/o Us Trendy clips - c/o Ladybird Likes socks - Tutuanna (Japan) shoes - c/o YesWalker It's no secret to anyone who's been reading my blog for a while that I'm really into brains. Well this video from ASAP science is an awesome exploration into the ways that just thinking can physically change your brain. Let me know your thoughts on it!

Panda Bears and Flowers / Clever Hans

Yep, it happened again, I murdered another plush toy to make a cute bag out of it. Inappropriate-guilty-feelings aside, I am actually so happy with this panda bear backpack. And I bought him for $3 from an op shop (yes, it's a male panda bear), so at least there were no sentimental attachments there. If you missed it the first time around, I wrote up some instructions on how to make a DIY plush toy bag here. The only difference with this one is that I added two straps (thrifted belts) instead of one! My pretty floral blouse & red skirt are both from Sheinside! Many thanks to Sheinside for providing them to style! blouse - c/o Sheinside skirt - c/o Sheinside socks - Shop With Romi shoes - c/o Yes Walker bag - DIY hat - c/o Wholesale If you're a casual reader of science stories (or have joined IFLS on facebook) you may have heard people talking about "blinding", or that an experiment was not reliable because it wasn't "blinded" or even "double-blinded". You may have thought, what on earth does "blinding" mean and more importantly, how on earth does anyone know what's happening if no one can see what's going on?? Well "blinding" is one of the most important concepts to science. Human beings, clever as we may be, are unfortunately very susceptible to something called bias - that is, seeing what you want to believe. That's where the story of Clever Hans comes in. Clever Hans was the name of a horse who lived in the early 1900s. His owner claimed that Clever Hans could not only count, but could also do complex maths problems and understand German. His owner would ask him questions, and Clever Hans would answer by tapping his foot. His owner paraded his horse around Germany, showing off his apparent skills. Clever Hans performing in the 1900s in Germany. Also check out all them boater hats - I'd be so trendy if I were to go back to 1906 ;) (Image source) Clever Hans was investigated by veterinarians and teachers. They removed the audience to make sure Clever Hans wasn't getting cues from them, and they even used different questioners (other than the horse's owner) to rule out the possibility of fraud. Then they made a realisation - if the person asking the questions knew the answer to the questions, then Clever Hans would get the right answer 89% of the time. But if the person asking the questions didn't know the answers themselves, Clever Hans was only right 6% of the time. It seemed that Clever Hans was clever in a way, although he didn't know how to count or do maths - he had learnt to tap his foot whenever the questioner expected the horse to tap its foot. Take away the expectations of the questioner, and the horse had no idea. This was a very important observation for science and where the idea of "double blinding" comes from. Now scientists make sure, especially in fields where animals or humans are being measured, that not only does the participant not know what condition they are in, but the experimenter is also "blind" to the conditions of the experiment as well. Only at the end of the experiment, when all the tests have been done, are both the subject and experimenter allowed to know what was really going on. And that's your neat science fact of the day. p.s. I announced another giveaway earlier today! Enter here if you haven't already.
