Physicist suggests ‘quantum foam’ may explain away huge cosmic energy

 

Steven Carlip, a physicist at the University of California, has come up with a theory to explain why empty space seems to be filled with a huge amount of energy—it may be hidden by effects that are canceling it out at the Planck scale. He has published a paper describing his new theory in the journal Physical Review Letters.

Conventional theory suggests that should be filled with a huge amount of energy—perhaps as much as 10120 more than seemingly exists. Over the years, many theorists have suggested ideas on why this may be—most have tried the obvious approach, trying to figure out a way to make the energy go away. But none have been successful. In this new effort, Carlip suggests that maybe all that energy really is there, but it does not have any ties to the expansion of the universe because its effects are being canceled out by something at the Planck scale.

Ele perguntou: para que é que eu quero 10 Ferraris, 20 relógios de diamante ou 2 aviões? O que devo fazer pelo meu mundo?

Então, passei fome, trabalhei no campo, sobrevivi às guerras, joguei futebol descalço, não tive educação e outras coisas ruins, mas agora quero agradecer ao futebol, posso ajudar meu povo. Ele construiu casas, um estádio, comprou roupas, sapatos, comida para pessoas de extrema pobreza. Além disso, dá uma mesada de 70 euros para todas as pessoas de uma região muito pobre do Senegal que contribuem para a economia familiar.

Não é necessário exibir carros de luxo, mansões enormes, viagens, muito menos aviões; prefiro que os meus recebam um pouco do que a vida me deu.

La Educación Infantil en Europa: jugar todo el tiempo y aprender a leer a los 7 años

 

 

 

 

 

 

 

Acabo de estar en Suiza y quisiera contar lo que he visto sobre el sistema escolar en la etapa 3 a 6, lo que en España es Educación Infantil de segundo ciclo.  Se trata de un sistema similar al de Austria, Holanda, Finlandia y prácticamente todos los países desde ahí hacia el norte.  Nadie diría que son países “retrasados” en ningún aspecto, ni cultural, ni social ni económicamente, ni por supuesto académicamente.

El efecto de las nalgadas y correazos en la salud de los niños

El año pasado escuché por la radio a tres periodistas de Panamá que recomendaban a los padres y oyentes volver a utilizar el castigo físico sobre sus hijos. Según estos periodistas la rebeldía, el descontrol y los problemas de la juventud se deben a que los padres de hoy no son capaces de pegarles a sus hijos cuando se lo merecen. Eso no fue todo.

El periodista más popular de los tres, dijo que los correazos y chancletazos no han matado a nadie y que ni fiebre les dan a los niños cuando se lo merecen. En otro programa, una de las periodistas le dijo a su audiencia de la mañana que el éxito de su vida profesional se lo debe a los castigos físicos que le dio su padre y que gracias a esa disciplina ella es hoy una mujer de bien.

El tercer periodista fue aún más osado y sugirió a los padres no hacerles caso a las recomendaciones de los psicólogos de evitar pegarles a los niños porque después se trauman, y aseguró además que a los niños nada les pasa cuando les dan unos buenos correazos por portarse mal.

La narrativa de los periodistas es una muestra del pensamiento imperante no solo en la sociedad panameña sino en todo el mundo. Así lo demuestra el último estudio publicado por UNICEF1, el cual reporta que el castigo físico es la forma de “disciplina” violenta más utilizada en el mundo y que el 80% de los niños de 2 a 14 años ha recibido algún tipo de castigo físico.

Harvard University Physics Chair Subir Sachdev: “It is Very Harmful to Make False Claims About India’s Contribution” to Science and Technology

 

 

 

 

 

 

 

 

 

CAMBRIDGE, MA— Prof. Subir Sachdev, the Herchel Smith Professor of Physics and Chair of the Department of Physics at Harvard University and one of the top physicists in the area of quantum physics in the world, called on Indian scientists and academicians to speak up against any effort to stifle truth and science even if it puts funding of their institutions in potential jeopardy.

The pediatrician recommends weaning because breast milk has lost its effectiveness. The dentist to prevent the baby from having cavities. The Mother-in-law so he doesn’t get The educator recommends weaning for baby to adapt faster at school. The psychologist for the child not to be infantilizada The Co-worker at the end of maternity leave is easier for mom. The nutritionist recommends weaning for the baby to eat better. The Professional of any medical specialty to be able to write a treatment for mother The husband so that the wife no longer complain of fatigue. Sleep consultant recommends weaning so the baby sleeps all night. Fonoaudióloga for child to start talking at once. The neighbor because she thinks it’s ugly big baby

Do you know what these recommendations have in common? They all need solid scientific evidence to justify them. They are nothing but a personal or professional opinion supported on questionable arguments and of dubious intention. They are just a sample of ignorance and prejudice around breastfeeding. These are some of the obstacles we will need to face to make it For Society in general it is much more comfortable to play the guilt of breast fatigue on the demand of the baby than to provide the necessary support and support so that this mother can fulfill the arduous and challenging task of creating a healthy human being in all aspects

As long as our culture continues to view breastfeeding as the root of all mother evils and weaning as the ideal solution of all its problems, we will continue as a species, moving away from our essence, creating fragile and fragile bonds with our offspring .

In any case, the weaning decision is the mother and the baby, exclusively, and not the doctor or society. So let’s stop selling illusion to breastfeeding mothers, since breastfeeding is rarely the real problem and weaning is no guarantee of anything. Mothers Need effective support, not guesses. Be Tribe and don’t stumble
