  • No, it doesn't work for you
    We've all heard this ever. Some may even have used this argument: "it works for me." It seems that it works as a defense of the effectiveness of everything. From homeopathy to ouija including NLP or MMS. If you've tried it and you've seen that it works and maybe you even know more people that say that it works, we could say that its effectiveness is proved, right? Let's see why this argument could be wrong.
  • "Science is just an opinion," said the postmodern
    "Science is just an opinion, as valid as any other," said the postmodern guy in a tweet sent from his smartphone with 4G connection while the MEPG stream received through a fiber optic cable was being decoded to stimulate the electrodes that will polarize the glass that will shape the image of Deepak Chopra on his TV. The same MPEG stream was also being decoded to a series of electrical impulses that cause disturbances in the air that reached his ears to become the sound of the words of the Indian spiritualist.
  • Coriolis Effect and drains, again
    It's a widely held belief that water falls down the drain turning in the same direction in one hemisphere of the Earth and the opposite direction in the other hemisphere. I remember, an X-Files episode (which implies that this happened about 15 years ago) where Mulder saw the water falling down the drain turning clockwise and that, Scully, is impossible because we are in the northern hemisphere and water always turns counterclockwise here.
  • My complaint to TED about TEDxValenciaWomen
    La pulga snob - Sexista This Saturday, December 1st, a TEDx event was held in Valencia: TEDxValenciaWomen. Two other TEDx events were held this weekend in Spain: TEDxGalicia and TEDxPonferrada on Friday, but I couldn't pay attention to those two because it was a weekday, I'll wait for the videos to be published. TED events are a set of conferences where speakers can talk about different topics. Originally these were mostly technological topics, as the name suggests.
  • And what does science say about that?
    You probably have heard some popular belief with a supposed scientific base of the type of humans use only 10% of their brains, you can kill somebody dropping a coin from a tall building, hair and nails continue growing after death or water drains backwards in the other hemisphere. Surely that you have heard more than twenty, but twenty are solely those that a recently published document (a little lacking in references) tries to solve.
  • Hex counting
    In the latest comic strip of Raulito el friki the hexadecimal numeration is mentioned and some readers are sorry not to dominate it. Here comes the explanation. The decimal numeration begins with 0 and when the 9 -the last symbol- is reached, the next is 0 and we carry 1 to add it to the following more significant digit; i.e., if we add 1 plus 9, the result is 0 and we carry 1 for the following digit.
