The noun algebra comes from Arabic word al jebr, meaning "reunion of broken parts," which appeared in the title of mathematician al-Khwarizmi's famous book on equations.

Arabic, actually. In the 9th century, during the intellectual flourishing of the Islamic Golden Age, zero became fully integrated into mathematics. This critical development was spearheaded by the Persian scholar Muḥammad ibn Mūsā al-Khwārizmī, celebrated as the father of algebra. In the House of Wisdom in Baghdad, Al-Kwharizmi developed an Arabic numeric system with the number zero, called in Arabic ‘sift’.

It's a grave situation they are faced with.

That would happen if you did not eat enough - you were calorie deficient. For most of us, our excess weight is due to excess intake, so if you reduce the size of your portions, the weight will come off. Of course, you can hasten the loss if, in reducing portion sizes you abandon the nasties as facthunter has mentioned.

Normally our bodies use carbohydrates for energy. You know all about the levels of glucose in your blood. Glucose is the carbohydrate we use. If we consume too much carbohydrate, our liver converts the excess to fat, which we store in various paces around the body. When we go on a diet, we cut back on our carbohydrate consumption. Our supply of glucose drops, so the body starts breaking down fat to make glucose. A product of that breakdown are chemicals called ketones. They are classified amongst the fats. The process of formation of ketones is called ketosis. Ketones are volatile substances and if the concentration in the blood gets a bit high, they can escape from the blood in the lungs and we breathe them out. This give the breath a distinctive smell - not the small of usual bad breath, or from the flavours in alcoholic drinks or onions or garlic.

How about we call it an average loss of a kg per week over six months? One should set a target and hope for a bullseye, but accept a near miss as being a success. I agree that too much weight loss will result in ketosis, but any metabolism of fats will produce ketones. Perhaps it is the exercise like walking or swimming that prevents the loss of muscle mass.

I don't hold with those "diets", mainly because they seem to require you to buy in all sorts of ingredients you've never had before to make dishes you don't know if you will really like. My guide to weight loss is quite simple. Reduce the serving size of everything, and possibly serve your meal on a bread & butter plate or entree plate. Find out what the serving size is for the your basic meat and two veg. Mashed potato - 100 gm; veggies 1/2 cup else 100 gm, and meat about 250 gm. Try to limit your intake of foods containing flour, and, of course, try to avoid sugar as much as possible. Have treats in small servings. Probably most of your weight gain was due to pigging out on treats. Don't eat a complete take-away serving. Save some for Ron. You also need a large helping of patience. After the initial quick weight loss, which is mostly water, you are doing good if you average one kilogram loss per week. Don't forget that you will reach plateaux when you won't lose weight for a week or two. Expect that. Just think. If you were able to lose one kilogram per week over six months, you'd lose close on 30 kgs. I wouldn't suddenly start heavy exercise. For a start, your knees and pelvis won't handle it. Try walking 10 minutes out/ten minutes back for a month, then 15/15 for a month. It's the time taken in moving that's important, not the distance covered or the steps taken.

The problem nowadays is that we don't get reporting of events, we get opinions, and if you own the media that the opinion is broadcast on, you can block out differing opinions.

But what if one is an aviation hanger-on with no use for those sort of things? There has to be another way to give support. By the way, very shortly after making my donation to Wikipedia I received an email thanking me for the donation and including receipt details.

If I want background noise while I'm working on the reno, I listen to ABC Classical, but when I'm driving I like to listen to the conversations. I don't like listening to News Radio - news nowadays is too depressing. I also like listening to the cricket since the ABC commentators don't talk statistics between each ball and over. Listening to the ABC commentary is like going to the cricket for a day out with your mates.

No chastisement involved. I didn't know that until I looked it up to post a reply.

Ian never got back to us about contributing to the costs of this site, did he.

An equilateral triangle is a unique isosceles triangle in which the three sides are equal. All other isosceles triangles only have two sides equal. That is much the same as a square being a unique type of rectangle in which all sides are of equal length, or a circle being an ellipse in which the major and minor axes are equal in length.

Of course it would. Technical drawing, or draughtsmanship is simply the use of basic geometric shapes and geometric rules to creating pictures of the object on wants to represent. Actually a lot of newer Computer-Aided Drawing software is based on basic three dimensional shapes that are morphed into the desired shape by "cutting" or merging boundaries.

What's the point of learning that? I'll never use it in real life. How often has that been heard in a whining voice from a reluctant student? Well today I learned a practical application using a property of an isosceles triangle. Which triangle is the isosceles triangle? It's the one that has two sides of equal length. I learned how to check that the angle in a corner of a box or frame is 90 degrees using two sticks of wood. Here's the video I found that introduced me to the concept and showed me how to make a tool to apply the concept. I knocked the tool up in about half an hour, and have thrown it into my tool kit to use on Saturday when I am assembling the frame of a workbench I'm building at the Men's Shed.

I use Wikipedia extensively. It's free to use, but there's nor such thing as a free lunch. At the moment Wikipedia is asking users to make a donation to support its continued existence. If you use Wikipedia a lot, and you have gained a lot of knowledge from accessing it, then seriously consider making a donation.

Thank you for that bit of scatology. I find those mouse-like droppings and I was fearing that I might be getting invaded by mice despite my efforts to seal ground level access points. I'll have to inspect these droppings and look for the white tail. Reptiles have a common alimentary and urinary exit point, don't they? Perhaps the white bit is dried urine.

For many years since I left the police, I put on weight. A couple of years ago, I was up to about 130 kgs. I've since lost about 20 kgs which is showing as a thinner face, arms and legs. However, although I feel that I have lost abdominal fat, being so big around the gut before means that the skin bulges over my belt like a deflated inner tube. So a pinch test would not be too accurate in my case.

The word 'gay' didn’t just one day adopt that meaning as an offensive comment made about flamboyant homosexuals. The word has always had a second meaning that dates back to 1637 where the secondary meaning was defined as being addicted to social pleasures and dissipation. In other words, the gay life was a life of loose morals and so males and females who were inclined to leading immoral lives were said to be gay. It only took three hundred more years for the word to refer to male homosexuals. When the term gay blade first began showing up in literature, it had nothing to do with being addicted to social pleasures. It referred to a gallant young man who was usually adept as a swordsman. The word blade is from the Middle English word blæd which meant sword in the late 1300s, and referred to a man by the 1590s, hence the play on words. The word gay is also from the Middle English word which meant impetuous, lively, and merry. From this comes the expression gay blade and, many gallant young men who were unusually adept as swordsmen back in the day were impetuous, lively, and merry as well as skilled.

So I wouldn't hear a murmur out of you if I gave you a swift kick in the bum? I know that was a trivial comment, but it beggars belief that a person who believes they have been done wrong should wait for years before complaining. I remember back in the Dark Ages of police investigating allegations of sexual assault, one choice piece of evidence in support of the allegation was "early complaint". That means the alleged victim told someone within a short time of the alleged incident. That's one of the reasons I was wary of the Brittany Higgins matter - lack of early complaint.

Back to topic. YouTube is flooded at the moment with videos announcing Trump's latest announcement, or videos explaining how many of his MAGA-directed promises will adversely affect both Americans at home and US diplomatic relations around the world. If we started posting links to all those videos, and to other media items, this thread would soon be running into the thousands of posts, and that's without any of us commenting on individual posts. At least we can say that the owners of YouTube must be making a motza from all this Trump-related stuff.

The Chinese must be laughing their heads off behind closed doors about how their sabre rattling and jeering is stirring up the Yanks. Of course the Chinese won't rely on military action. Why should they? Although they have a huge population, they don't need more land. What they want are raw materials and markets for what is produced from those raw materials. This week the ammunition in the Sino-US trade war is computer chips.

Not if it was a pan, or it was a long drop.

Mum gets the Sunday Telegraph. She's a keen follower of horse racing, so she removes the Punter section for herself. She takes out the "magazine" inserts to send down to the staff meal room for the carers to read. She sends the sport section to another resident. That leaves the 'news' section which I grab after she has read it. It only takes a short time to read the 'news' section as the majority of pages contain ads for Harvey Norman and some homewares mob. Then there is the Right Wing drivel and stories about the multi-million dollar real estate dealings of celebrities. After that there are the social scene reports. What a waste of ink and paper!
