Seeing is believing, but it's definitely more entertaining to re-create the experience first hand with the right tools.
The Instagram.com/PhysicsFun compiles many of the most interesting toys available for purchase and are wonderful instruments to study the laws of our universe and lighten up the mood of any science lover.
The Silver Swan is an automaton dating from the 18th Century and is housed in the Bowes Museum, Barnard Castle, Teesdale, County Durham, England which was acquired by John Bowes, the museum's founder from a Parisian jeweler in 1872. The life size swan is a clockwork driven device that includes a music box and sits in a "stream" that is made of glass rods and is surrounded by silver leaves. Small silver fish can be seen "swimming" in the stream which adds a remarkable effect to the overall realness of time.
A rare species of cuttlefish called Metasepia pfefferi, more commonly known as the Flamboyant Cuttlefish shows off his true colors in this remarkable video from the Aquarium of the Pacific in California. This species of cuttlefish occurrs in tropical Indo-Pacific waters off northern Australia, southern New Guinea, as well as numerous islands of the Philippines, Indonesia and Malaysia. The flesh of this colorful cephalopod contains unique acids, making it unsuitable for consumption and thus, highly poisonous.
You’re probably familiar with the TV or movie plot device where a character is conked on the head, loses memory or identity and then gets conked again and memory is restored. Classic examples are in the 1951 Tom and Jerry Cartoon Nit-Witty Kitty and the movie “Clean Slate.”
We’ve known that bacteria live in our intestines as far back as the 1680s, when Leeuwenhoek first looked through his microscope. Yogurt companies use that information in the sales pitch for their product, claiming it can help keep your gut bacteria happy. The bacteria growing on our skin have also been effectively exploited to sell the underarm deodorants without which we can become, ahem, malodorous. Until fairly recently our various microbes were thought of as freeloaders without any meaningful benefit to our functioning as healthy human beings.
Giving feedback is unquestionably one of the most challenging tasks for any leader, as it can be painful to both the giver and receiver. It is nonetheless invaluable: Research has shown that employees recognize the importance of feedback – whether positive or negative – to their career development.
Many even welcome it, provided it’s given well. One study of nearly a thousand employees both in the U.S. and abroad found that 92 percent believed that negative feedback is effective at improving performance – “if delivered appropriately.”
The recent finding that telling lies induces changes in the brain has stimulated a number of misrepresentations that may wreak more harm on our understanding than the lies on which they report. CNN’s headline runs, “Lying May Be Your Brain’s Fault, Honestly,” and PBS reports, “Telling a Lie Makes Way for the Brain to Keep Lying.” These stories are based on a study from University College London using a brain imaging technique called functional MRI. The authors report that as subjects tell lies, activation of the amygdala, an area of the brain associated with emotion and decision making, actually decreases, suggesting that subjects may become desensitized to lying, thereby paving the way for further dishonesty.
Most of us considered microbes little more than nasty germs before science recently began turning our view of the microbial world on its head. A “microbe” is a bacterium and any other organism too small to see with the naked eye. After decades of trying to sanitize them out of our lives, the human microbiome – the communities of microbes living on and in us – is now all the rage. And yet, some insist that we can’t really call microbes “good.” That’s nonsense.
