Algo sobre los caminos al conocimiento... - Ciencias II énfasis en física. Secundaria El ser humano gracias a su facultad de raciocinio, se ha cuestionado incansablemente acerca de todo en este universo en el que habita, desde aquello que lo rodea que es físico y material, hasta aquello que no es tangible, que solo habita en el pensamiento, en la abstracción y de lo que puede solo especular y teorizar. Y en su labor por tratar de responder estas preguntas, ha tomado muchos caminos que lo han llevado a otras esferas de conocimiento. Algunos de estos caminos son por ejemplo: La filosofía, la ciencia, la metafísica, la religión, la teología y el arte. Posição política pode ser determinada pelo cérebro, indicam pesquisas - Galileu Há quem prefira perder o amigo do que perder a alfinetada em mês de eleição. Mas, antes de deletar aquele tio extremista no Facebook, fique sabendo que a posição política dele pode estar relacionada ao tamanho de uma região específica do cérebro. Em 2011, cientistas britânicos da University College London publicaram um estudo afirmando que as visões políticas estão relacionadas ao tamanho de partes específicas do cérebro. Basicamente, pessoas mais conservadoras têm uma amígdala cerebral maior e pessoas mais liberais têm massa cinzenta em maior quantidade no córtex cingulado anterior. A amígdala é responsável pela identificação do perigo, enquanto o córtex cingulado anterior reconhece as situações onde o autocontrole é necessário. A Universidade Estadual do Arizona também fez uma pesquisa nessa área, perguntando a democratas e republicanos se o desemprego aumentou nos Estados Unidos entre 2008 e 2010 (ano em que a pesquisa foi realizada).

CUADRADOS MÁGICOS ~ RETOS MATEMÁTICOS Los cuadrados mágicos son distribuciones de números en celdas que se disponen formando un cuadrado, de forma que la suma de cualquiera de las filas, de cualquiera de las columnas y de las dos diagonales principales da siempre el mismo resultado. Al número resultante se le denomina "constante o suma mágica". El cuadrado mágico más pequeño es el que tiene 9 casillas, de orden 3 o de tamaño 3x3, Para iniciar puedes probar con los siguientes retos matemáticos en los que se pide que trasladen las tarjetas de tal manera que cada fila, cada columna y cada diagonal principal sume 15 : HISTORIA Se dice que el emperador de China Yü estaba en la orilla del río Amarillo cuando una tortuga salió de las aguas. Sobre su caparazón, la tortuga llevaba impresos extraños símbolos, que el emperador se encargó de descifrar. Eran los números del 1 al 9 dispuestos armoniosamente en forma de cuadrado: al sumar los tres números de cada fila, de cada columna o de cada diagonal el resultado era siempre el mismo.
New AI can work out whether you're gay or straight from a photograph Artificial intelligence can accurately guess whether people are gay or straight based on photos of their faces, according to new research that suggests machines can have significantly better “gaydar” than humans. The study from Stanford University – which found that a computer algorithm could correctly distinguish between gay and straight men 81% of the time, and 74% for women – has raised questions about the biological origins of sexual orientation, the ethics of facial-detection technology, and the potential for this kind of software to violate people’s privacy or be abused for anti-LGBT purposes. The machine intelligence tested in the research, which was published in the Journal of Personality and Social Psychology and first reported in the Economist, was based on a sample of more than 35,000 facial images that men and women publicly posted on a US dating website.
Why IQs Rise When Nations Experience Rapid Economic Development By Louis Putterman Just in case you haven’t heard this before, I’ve got some information for you that you might find a bit troubling. In their 2006 book titled IQ and Global Inequality, intelligence experts Richard Lynn and Tatu Vanhanen report that setting the average measured IQ in the U.K. at 100, people in the U.S. had average IQs of 100 and 98, respectively. People in the Central African Republic, Mali and Kenya had average IQs of 64, 69 and 72.
Alternative Medicine Kills Cancer Patients, Study Finds Chiropractic, homeopathy, acupuncture, juice diets, and other forms of unproven alternative medicine cannot cure cancer, no matter what some quacks might claim. Unfortunately, vulnerable cancer patients turn to these charlatans every year rather than visit real doctors, hoping for a miracle treatment to purge them of their monstrous disease. But as a new study published in the Journal of the National Cancer Institute makes painfully clear, as a treatment for cancer, alternative medicine does not cure; it kills.

Climate deniers blame natural factors; NASA data proves otherwise Climate scientists tend not to report climate results in whole temperatures. Instead, they talk about how the annual temperature departs from an average, or baseline. They call these departures "anomalies."
