![]() ![]() If they do add up to exactly 180 though, then the lines are actually parallel. What Euclid is saying is that eventually, the lines are going to intersect somewhere, sometime. Let's also say that ∠ α and ∠ β add up to a number that's not 180°, the sum of two right angles. Let's say we have two lines and another line that crosses both of them, like in the picture above. The original version of the parallel postulate goes something like this: if a straight line that crosses two straight lines makes two angles on the interior whose sum is less than the measure of two right angles, the two straight lines will intersect on the same side as those angles.Īre your eyes crossed yet? Because ours totally are.īasically, it all boils down to that transversal thing we were talking about earlier. It's like Geometry in Wonderland, and we'd suggest not going down that rabbit hole just yet. Mathematicians have even shown that there are weird types of "non-Euclidean" geometry where the parallel postulate isn't true. ![]() It's not neat and simple like the others, and it can't really be proven. The fourth says that all right angles are equal. The first three talk about lines, line segments, and circles. And when they do, who you gonna call? Not Ghostbusters, that's for sure.Įuclid talked about five basic postulates. Remember when we talked about postulates a little while ago? Those bad boys will come back to haunt you. One of the many things Euclid did was start out with a bunch of basic postulates about the nature of geometry. A lot has happened in the last 2300 years.) Only with funnier jokes and more pop-culture references. So really, Euclid was the first to Shmoop geometry and we're just following in his footsteps. But he gathered up all the useful stuff that folks had been talking about for a while and presented it in a pretty comprehensible way. Well, not all of it, and he didn't exactly invent it. He practically invented geometry back around 300 BCE. It's sort of a miracle we haven't talked about him yet, since he's basically the father of modern geometry. Cue thunderous applause and a few rogue tomatoes thrown by disgruntled geometry students. ![]() Let's all give a big thank you-yes, a thank you-to Euclid of Alexandria. We've covered a lot of geometric ground already, but we still haven't paid proper tribute to the guy who got us into this whole mess. ![]()

![]() ![]() Or just use the PLA, as it is bio-degradable, comes in 5 colors, and is available here. The geeks at our lab keep rolling out new colors and new materials on a regular basis, so follow our web site and discussion forum for any new cool stuff. So basically all standard 3D printing materials. The default material is 1.75 mm PLA, but the miniFactory™ 3D can also handle ABS, Nylon or Laywood. Oh yeah, and you can’t make your creations breathe. So extra dimensional worm holes are still a no-no, but you can make tools, miniature space ships, weighed dice, doorknobs, fake teeth or hypno toads. There are very few limitations, other than it must fit on the printing surface and that you can make a 3D model out of it. Pretty much anything you can come up with. The miniFactory™ 3D software turns a 3D-model into instructions for the printer, which it then follows layer by thin layer finally producing your yellow Pikachu (that is what you are going to print first, isn’t it?). So instead of spraying ink on paper it creates three dimensional objects by melting plastic filament on very fine layers stacked on top of each other. The new, improved miniFactory™ 3D printer 2.0 is in production and will revolutionize 3D printing again.ĭeliveries start in April 2013 and you can pre-order yours now! The miniFactory™ 3D beta was a huge success and sold out quickly. As long as it fits the printing area, you can pretty much create anything: a robot, a game token, a phone cover or a Millennium Falcon with a banana for scale. The miniFactory™ 3D printer is safe and easy to use: just choose a model, or create your own, and the printer will turn it into a tangible three dimensional thing. It turns your imagination into reality easier than you ever dreamed of. MiniFactory™ 3D printer is a 3D printer for everyone. miniFactory™ 3D printer is designed for home users, hobbyists and educators. Note: When dealing with resins, make sure to wear protective equipment including appropriate eye protection and gloves.The miniFactory™ 3D printer is a complete 3D printer starter set with which you can take your first step into the magnificent realm of 3D printing technology. This method will create a chemical bond, just as if the part was printed on your SLA 3D printer, but is only applicable to small bonding surfaces as the low power light pen cannot penetrate the model deep enough to create a strong bond. ![]() To solidify the resin and bond the parts, use a 5mw UV laser light pen (405nm wavelength) and direct it to the bonding area around the parts. Join the parts and wipe off any excess resin that might spill out around the edges. Pour a small amount of resin into a tray from the bottle or cartridge, use a dropper or syringe to pick it up, and place it onto the surface to bond. CA has moderate impact strength, but is not recommended for high-impact applications.įor smaller prints you can also simply use the liquid resin from your SLA 3D printer. Clean the part thoroughly before applying it to the surface, as CA does not bond dirty surfaces well. The next option is cyanoacrylate (CA, or Super Glue), which creates a quick, reasonably strong bond making ideal for small- and medium-sized parts. Read on for a step-by-step walk through the process, from splitting your model to post-processing for a professional finish. This guide will focus on creating large multi-piece stereolithography (SLA) 3D printed models using chemical fastening. Mechanical fastening: Add screw thread or pockets to functional engineering parts that require a robust mechanical connection or if you need to repeatedly attach and detach components. When selecting a bonding method, your primary consideration should be the strength of the bonded joints, which is dependent on the ultimate use case of the parts:Ĭhemical fastening: Use a bonding agent for art, scale models, and complex shapes that are not meant for functional use and to sustain impact. This is the case when multiple or opposing surfaces need to be free of support marks, a design has complex overhangs, or a model contains cavities that would trap the liquid resin inside.ģD printing multiple pieces also opens up new opportunities, such as creating multi-material assemblies or combining rigid and flexible 3D printed parts to simulate overmolding. ![]() Splitting a part can also be the best way to get a high-quality result, even if the whole part could fit into a single build. Just as assemblies such as your smartphone or even a road bridge consist of many individual building blocks, splitting a model into smaller parts that can be combined after printing is a great solution for 3D printing large objects that don’t fit on a build platform. Don’t own a large format 3D printer yet? When determining what’s possible with a compact desktop 3D printer, think beyond the build volume. ![]() ![]() ![]() Nobody wants to be eating this.Many recipes will call for a bunch of thyme but it can be hard to really know what that means. Leavings from any animalsx that you might own or that could make their way into your garden.Bird droppings - This is especially important if you cater for birds in your garden, and in this case, it may be better if you grow your herbs inside.Pesticides and other chemicals - These could be transferred to your dish through the herbs, and these are not safe for consumption.However, due to the fact that many of these herbs are served uncooked, you will need to ensure that where they are being grown is protected from: You will be able to grow fresh herbs through a sunny window area or in your garden with ease. What You Need to Know About Growing Herbs The stem is considered to be quite fleshy, and basil can be snipped directly from the plant or simply clipped from the stem. The leaves are quite glossy, and they are evenly veined. So, for the best results when it comes to flavor, you should take your leaves from the higher end of the plant.īasil leaves that are fresh will be tender on the palate, which is why they often make a great addition to things like salad and sandwiches.īasil in itself is a pretty plant, and this is one of the reasons why many people choose to grow it in their gardens. This is where most of the fragrance and flavor will be, which is why it is the best part of the herb to use. A Sprig of Rosemaryįresh rosemary sprigs look similar to the needles that you would find on an evergreen tree, and they are filled with flavor and have a pleasant smell.Ī sprig of rosemary is 3 inches or less from the terminal stem, which is the top of the plant. You will probably need to rinse the thyme before using it for cooking to get rid of any excess soil or sand. These plants are known for being quite delicate, and they are typically grown low to the ground. The leaves are really small and are around ¼ inch in length. If the stem does snap while you are doing this, then the entire thing is likely tender enough for you to eat it, and you can chop up the entire amount with the leaves. Thankfully, this is a herb that is really easy to strip, and all you need to do is grab the thyme near the top, pinch it tight, and run your fingers of your other hand down the stem to strip away the leaves. ![]() If your recipe is asking you to use a sprig of thyme, it is referring to the 3 inches that are at the terminal end of the stem. Thyme is a small and leafy herb that will grow in small clusters of around 3 to 5 leaves on a woody stem. This will help you to further understand what your recipe requires. ![]() We are going to tell you all about the different requirements for obtaining a sprig of some of the most commonly used herbs below. Generally, a sprig is defined as a 2 to 4 inch piece of the herb plant, but how do you get this from certain herbs? ![]() When a recipe requires a sprig of herbs, it is referring to a specific amount of herbs. There are lots of things to consider, and we are here to answer all of your questions and tell you exactly what you need to do when a recipe requires a sprig of herbs. There are also some herbs that are difficult to separate from the stem, and you might be wondering what sort of method you need to be using to remove them. You will need to know exactly how many leaves a sprig is referring to, and how you can add this amount to your dish. Something that you might have come across in a recipe is a sprig of a certain herb, but what does this mean. ![]() ![]() This is a very rough indicator, though, as it is extremely sensitive to outliers. Knowing the location of a variable is not enough for our purpose as we miss an important information: how close are the values to the mean? The simplest statistic to express the spread is the range, that is the difference between the highest and lowest value. Considering that extreme values (very high or very low) are usually known as outliers, we say that the median is more robust than the mean with respect to outliers. For example if we take the same values as above (1 - 4 - 7 - 9 - 10), the median is equal to 7 and it is not affected when we change the highest value into 100. The median is always the central value in terms of positioning, i.e., the number of values above the median is always equal to the number of values below the median. Otherwise, if the number of values is even, we take the two values in the \(n/2\) and \(n/2 1\) positions and average them. If the number of values is odd, the median is given by the value in the \((n 1)/2\) position ( \(n\) is the number of values). The calculation is easy: first of all, we sort the values in increasing order. If we change the highest value into 100, the new mean is moved upwards to 24.2 and it is no longer in central positioning, with respect to the sorted list of data values.Īnother important statistic of location is the median, i.e. the central value in a sorted variable. For example, if we look at the following values: That does not imply that the number of values above the mean is the same as the number of values below the mean. In other words, the values above the mean and those below the mean, on average, are equally distant from the mean. The mean can be regarded as the central value in terms of Euclidean distances indeed, by definition, the sum of the Euclidean distances between the values and the group mean is always zero. The most widely known statistic of location is the mean, that is obtained as the sum of data, divided by the number of values: 16.8 Expressions, functions and arguments.16.2 Installing R and moving the first steps. ![]() ![]()

With the help of cast () function we will be able to typecast numeric or integer to character in. It allows you to add if-else logic to the query to form a powerful query. Instead, you should use tochar to format the date when you query it, or format it in the client application. In order to typecast integer or numeric to character in postgresql we will be using cast () function. The PostgreSQL CASE expression is the same as IF/ELSE statement in other programming languages.

![]() Bottom line, Adobe does not deserve your money for this application, which they clearly dislike within the company (when you make a bug report, it's interesting to note that it's called GoLive, not Adobe GoLive). GoLive CS2 crashes regularly for me several times a day, and has even managed to crash WHILE SAVING A VERY IMPORTANT FILE, which wiped out an entire day's work for me, causing me to redo it all. I want to warn you about GoLive - it is the most frustrating, least reliable, most crash-prone app I have used since switching to OS X. at the end of the day real web designers hand-code anyway! i'm sure both do what they do equally as well and you should use whichever one you feel most comfortable with. Whatever the differences between the latest iterations of these two old war-horses, it hardly matters. it just happens to be slightly less spaghetti-like than the code generated by golive! dreamweaver still generates horrible code spaghetti and takes about a hundred lines of said electronic pasta to do what you can hand-code in one. Then when using CSS for layout became the 'next big thing' golive was left behind, as macromedia started really pushing the fact that dreamweaver wrote 'clean, standards compliant code' and thus dreamweaver gained the reputation as being the professional's choice. that was back when both apps created their layouts using clunky, hacky, nested tables, built with horrible code spaghetti - when no-one really cared about concepts like standards compliance, as long as it worked on exploder and netscrape. I used to use golive way back in the days when it was called 'golive cyberstudio' and it was streets ahead of the similarly youthful dreamweaver at the time - at least in terms of ease of use. but it seems like adobe thinks there's life in the old dog yet. i'd thought golive was destined to be taken out the back and put out of its misery with adobe's gobbling up of macromedia. ![]() |
