  1. I think the knee-based pushups (and I will never-ever-ever consent to calling them "girl pushups") are good for strengthening the shoulders and arms. However, they don't do as much for the core, and I think that's at least half my reason for doing pushups!

    After my pregnancies, I couldn't do full pushups, and the thing that helped me get those back was doing full pushups on the stairs, with my feet on the floor. I'd do 10 with my hands on step 5, then after a week move down to step 4, and so on. That really worked. 

    I don't know how you'd transition from knees to feet effectively. I couldn't.

    I don't think that the book you linked is a product of OpenStax (which is affiliated with Rice University).  It looks like it is published through OpenIntro  which is a different organization.  

    I am not familiar with OpenIntro, but I have used some items from OpenStax.  I have not found any more typos than with other published materials, but I think the quality varies from discipline to discipline.  

    Oh, you're right. Thank you.

    I looked at their physics text, and not only were there typos, but sloppy notation and many errors in the example problem solutions. During my first 15 minute browse I submitted four errata and decided against adopting the text for my class.

    It's open source, so this is how it works. You get what you pay for.

    Ok, that's very good to know.

    Okay, this isn’t funny; there’s a real likelihood this is how humanity ends.

    Oh, that's not ok. Did we learn nothing from covid? Do not introduce the weird new thing into the population!

  5. We're using this textbook for DD16's AP Statistics course.OpenIntro Statistics: Third Edition by David M Diez (2015-07-02) https://a.co/d/82cWdtK

    We got a cheap used paperback copy. We like the way it explains things, and the order in which the ideas are presented. However, man could it have used a better editor!

    There are even occasional errors in the math! Missing words in sentences! We can use it, sure. But it's distracting.

    Is this common with open-source or free textbooks, in your experience? Maybe I went too cheap.

    I get it. I have a few pieces of advice for you.

    - Remember that you are angry at the quacks, not at their targets. Don't let your anger accidentally splash-over onto your friend.

    - Give advice when you are asked, in the proportion that you are asked for (1-2 sentences unless you are asked to elaborate). And pay close attention to whether or not there was an actual "ask" or just a topic and a pause in the conversation for "your turn".

    - Accept your role as 'one of many' sources of advice. Don't take it personally if she opts to follow another source at any point. She's allowed to ask you for an opinion as part of her 'gathering data' phase. It doesn't obligate her to take your advice in order to continue to have harmony in your relationship. Give her the gift of both harmony and data -- with no strings attached.

    - Treat her like the expert in her own life, and about her own body. Even medical professionals are not more 'expert' about these things than the people with the actual condition(s) are. Don't get the sense that because you are a generally level-headed, fairly wise, and well educated person -- that your evaluation of 'things' is smarter than her evaluation of 'things'. Consider the possibility that she may be right. Consider the possibility that on this topic she may be 'smarter' than you. Even if you struggle to truly believe that; even if she doesn't seem to believe that herself -- in conversation, act as if it is true. This will build her sense of being in her own driver's seat, and feeling competent to be in that seat. Even if you think she is making wrong turns, build that perception and refuse to undermine it. (That's how people -- eventually -- get enough experience to do a better job in directing their own lives.)

    This is so well-put.

    My youngest is my creative, artsy but also mathy kid. She made her own posters for her room when she went off to college and I was so impressed I said she should make some mathy ones for my classroom. She never did, until now. She made a bunch of function posters with her cool minimalist art, like the f(x)=x poster says "linear" up the side then has a skier going down a straight line slope. Quadratic has 3 cyclists (one flipping) in a y=x^2 bowl. They're just cool. I tell her she could sell a lot of these to math teachers. Then her sister, first year teacher of world history to 7th graders, said she should make her posters too. Youngest replied "I know her subject better." We had some fun thinking up ideas for world history (Vikings, castles), but she said those would take a lot longer to make.

    There. Is. A. Market! She needs an etsy shop or something! Those sound awesome.

  8. I'm sorry. That would hurt my feelings too. 

    I sometimes think Europeans travel more regularly than Americans. If I travel to one state in the US, I might not think to hop to the next state to see someone else. But in Europe, it was more routine to move between countries. Oddly enough, in or out of the EU didn't matter. And flights within Europe could be so cheap! 

    It's a different style of travel, I think.

    And while I think the bar with 16 and 17 year olds is that you never, ever, ever drive after even one drink, I think it's important to start laying the groundwork for what constitutes "after drinking."  I think people in general need to know that the guideline is at a minimum, not driving for an hour after one drink, or two hours after two drinks, and what constitutes a drink (one beer, a four ounce glass of wine, a shot of liquor), and they need to know that many mixed drinks contain more than one shot of hard liquor.  

    This has me thinking. Thank you. It's easy to end up with an abstinence only approach to alcohol. I need to include some more information around here myself.

  10. My 12yo ds is also quick at math. He's doing AOPS Intro to Algebra now. We set a timer for an hour per day. What he gets done, he gets done. I sit at the same table and keep him on task a bit, but he's getting better at that part (finally). We do math year-round, so I don't worry about finishing books in the school year window.

    It is rude, there’s a connotation that in rural Muslim areas men prefer sex with teen boys. I don’t think most people make the connection since 9/11 because soldiers had so much exposure to this sort of behavior in Afghanistan that it was less a condescending slur and more a series of actual news stories. But it definitely started as a condescending slur. 

    Well. That's a significantly ruder backstory than I anticipated. I'm sure most people who use it aren't going that far in their minds.
