Calories In A Bag Of Pop Secret

Disclosure Mathematics

Published yesterday published an interview with Capi Corrales recently honored with the award Laura Iglesias Romero in science communication. It talks about some of the evils of mathematics, such as lack of outreach work or lack of women.
Those who have had the pleasure to learn geometry with her remember her simple way of doing what before was incomprehensible to us.
It is also a woman committed to the world we live and the society around it.
copied and pasted a few paragraphs of the interview in regard to the presence of women in mathematics:

After the war, women no longer exist. Has killed many people and needs women giving birth and not at universities. So not only are not given opportunities, but that should not motivate them. It ninguneo history and memory of all those women from being a model for other women. A Franco did not care who knew that during the Republic had been women scientists, nor cared to have women doing research, because the woman who has investigated one or two children, not seven.




is due to several factors, but the key is the behavior of the mathematical community with women. In Spain we had a period in which both the mathematical community and from institutions has made an effort to make people aware of this problem, but this will begin to reverse, because socially being reversed. Girls and boys have no interest in thinking, to play, no curiosity. In the nineteenth century workers were needed and now need to consume, not people who think. I see women who are becoming more models, presidents who left to air the weddings of their daughters before the end of the race, that was not well seen before ... This will ultimately have an impact on state policies. If you do not give votes to policies that guarantee equal access, stop doing, and if left to do as yet not been developed for long enough, will be back in rights.



If you have time read it, will not be disappointed.

How Long Does It Take For Trichanomis To Be Cured

Tax Clarification on Russian Multiplication

In a previous post on the letter of the NIF slipped a small error. What you need to search the table of the letters is the remainder after dividing your identity card number by 23.
The main sticking with that found many people is that calculators are not normally an operation that returns the remainder of a division, decimals calculator out directly.
Windows Calculator, as science (Click on View / Science), can get us out of trouble with the MOD key:
Write the DNI
  1. MOD press the key type 23
  2. We click on the = key (or press the Enter key on your keyboard).
Failure to hand calculator windows desktop but a stream is a bit more complicated but can also be done:
  1. divide the number of ID card of 23.
  2. The result we subtract the part that is left of the comma, ie: the number without decimals. It should be something like 0 ,....
  3. Multiply that result by 23. That number is the remainder.
Anyway I do not understand the usefulness of a letter that anyone with a pocket calculator is able to calculate in seconds. What makes a safety extra point is calculated directly from the number?
