The ego version of Allah, not the dissolution of genders but a hyper-affirmation of both positives from either side.

I noted this same thing on the genetic splitting of the male/female root genes, Jesus and Judas essentially when in both male forms (as these are segmented hybridization of billions of years ago).

Carrying a child for 9 months is a literal nutrient drain for the mother. Statistically, the child that's conceived shortly after one is born will have a weaker frame. There's studies suggesting that second-born girls are usually more sexually attractive for this reason, while second-born boys are usually less so.

This >>16165372 may play a small role as well, but when the woman is in her teens and 20's, it doesn't matter as much. Nutrition plays a much, much bigger role then.

If you want multiple peak children, you need to space out the conception a bit more, like 3 years, and you need to make sure the mother is eating well to build up her nutritional reserves.

As the school year ends, many students will be only too happy to see math classes in their rearview mirrors. It may seem to some of us non-mathematicians that geometry and trigonometry were created by the Greeks as a form of torture, so imagine our amazement when we heard two high school seniors had proved a mathematical puzzle that was thought to be impossible for 2,000 years.

We met Calcea Johnson and Ne'Kiya Jackson at their all-girls Catholic high school in New Orleans. We expected to find two mathematical prodigies.

Instead, we found atSt. Mary's Academy, all students are told their possibilities are boundless.

Come Mardi Gras season, New Orleans is alive with colorful parades, replete with floats, and beads, and high school marching bands.

In a city where uniqueness is celebrated, St. Mary's stands out – with young African American women playing trombones and tubas, twirling batons and dancing - doing it all, which defines St. Mary's, students told us.

JuniorChristina Blaziosays the school instills in them they have the ability to accomplish anything.

Christina Blazio: That is kinda a standard here. So we aim very high - like, our aim is excellence for all students.

The private Catholic elementary and high school sits behind the Sisters of the Holy Family Convent in New Orleans East. The academy was started by an African American nun for young Black women just after the Civil War. The church still supports the school with the help of alumni.

In December 2022, seniors Ne'Kiya Jackson and Calcea Johnson were working on a school-wide math contest that came with a cash prize.

Because he's maybe one of the most remarkable great apes in history and we should probably be trying to make more. If you don't know, Kanzi is a now 40 year old male bonobo that has the most advanced human speech recognition ever recorded. As in we can talk to him. And not in a fake made up Koko the gorilla sense, like he genuinely has a vocabulary of around 3000 English words. He's currently 40 and that's the average life expectancy for a great ape like him living in captivity, so I'm curious if anybody knows if someone saved his sperm or his dna or something because time is kind of running out.

What's your level of math and what's your general background? The standard recommendation if you have taken a signals and systems class is Nise's Control Systems Engineering.

If you have a fairly strong math background and can skip straight to grad level stuff Brogan's Modern Control Theory is great for state space oriented control and Astrom's Feedback Systems has great coverage of PID and frequency domain control. Some people also really like Chen's Linear System Theory and Design but I'm not a huge fan personally.

I need some help, /sci/entists. I have this friend who I’ve been hanging out with for the longest time. We go out to bars and clubs. We pick up on girls and we aren’t afraid of being called non-PC. We both embrace the realities of the world and the natural order of things. We acknowledge that women are inferior to men. They are weaker biologically and that is how God intended it to be. Women are supposed to be the nurturers and the child-bearers. Men are supposed to serve as their protectors. My friend and I both acknowledge this to be true.
The only problem is that my friend doesn’t completely acknowledge reality like I do for they are a transgender male-to-female person who self-identifies as a lesbian. I tried to convince him several times that this is either a phase or they may be going through some trauma. They were never really abused by their parents or siblings so I have no idea where this desire to be a woman comes from. I also tried to explain to him that regardless of how much hormones they consume they will always retain that biological advantage. That God-given strength that all men were given.

I’m a man of science and I refuse to accept falsehood. You are either both male or female. Males are defined with a penis and females are defined with a vagina. There are exceptions, but they are too few to really consider changing the status quo. My friend always danced around this subject and told me that there is scientific evidence that estrogen could decrease a person’s muscles rendering them weaker than they were before. He tried to show me all of this supposed “evidence” yet it all comes off as some bullshit that the big pharmaceutical companies would use to sterilize children.

My friend was my homie. I thought we’d always be boys until the day he stopped talking to me. First it was for a couple of hours, then a few days, days turned to weeks, and weeks turned to months. Eventually, we haven’t spoken in years. It wasn’t until a few days ago that he sent a text message wanting to see what I’ve been up to. We chit-chatted for a while and I asked if he believed that he was a girl. He just told me that he was always a girl and that was the reason he stopped talking to me. He said that I was belittling him and never really cared about his identity. I just don’t get it. How could a brilliant scientific mind such as his fall victim to such pedophilic degeneracy? So, I asked this question to you: what evidence can you provide me that would finally convince my friend that he’s clinically insane? I have to save him from making a terrible mistake and it costs him his eternal soul.

The answer is that you're not getting your friend back and that's because you're too god damn stupid, OP.

Psychology is no more a science than your dumb boyfriend is a girl, so you aren't going to get anywhere with this.

How long will German universities be able to get away with using this for first year students, as their country becomes increasingly "diverse" and dumbed down by design.
(Americans in comparison use elementary books like Stewart for 1-2 years)

yes, and it's about teaching math differently, not teaching different math. There is no "different" math to teach, but there are many different way to teach math, get it? I'm sure you will

Are there any problem books for analysis you'd recommend?

Solving Problems in Mathematical Analysis (3 volumes) by Thomas Radozycki is very good for problems worked out in detail. Another nice set is the 3 volumes by Kaczor and Nowak. Both are quite useful for self-study in my opinion.
