And second, they often require relatively little prior knowledge, and offer the chance to think visually.

![]() ![]() Take a weekend hike with your family or spend an evening ballroom dancing. Maybe your workout routine includes various activities, such as walking, bicycling or rowing. Any amount of activity is better than none at all. Exercising in short sessions a few times a day may fit into your schedule better than a single 30-minute session. Shorter but more-frequent sessions have aerobic benefits, too. You don't have to do all your exercise at one time, so you can weave in activity throughout your day. Work your way up to 30 to 60 minutes of exercise most days of the week. As your stamina improves, gradually increase the amount of time you exercise. Then speed up to a pace you can continue for five to 10 minutes without getting overly tired. Give yourself plenty of time to warm up and cool down with easy walking or gentle stretching. As you begin your fitness program, keep these tips in mind: ![]() A written plan may encourage you to stay on track. Plan time between sessions for your body to rest and recover. Many people start exercising with frenzied zeal - working out too long or too intensely - and give up when their muscles and joints become sore or injured. In high-interval intensity training, you perform short bursts of high-intensity activity separated by recovery periods of low-intensity activity. Plan to alternate among activities that emphasize different parts of your body, such as walking, swimming and strength training. Cross-training using low-impact forms of activity, such as biking or water exercise, also reduces your chances of injuring or overusing one specific muscle or joint. Different activities (cross-training) can keep exercise boredom at bay. Plan to watch your favorite show while walking on the treadmill, read while riding a stationary bike, or take a break to go on a walk at work. To make it easier, schedule time to exercise as you would any other appointment. Finding time to exercise can be a challenge. ![]() Build activity into your daily routine.If you have an injury or a medical condition, consult your doctor or an exercise therapist for help designing a fitness program that gradually improves your range of motion, strength and endurance. If you're just beginning to exercise, start cautiously and progress slowly. Aim to do a single set of each exercise, using a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions. Being active for short periods of time throughout the day can add up to provide health benefit.ĭo strength training exercises for all major muscle groups at least two times a week. But even small amounts of physical activity are helpful. ![]() ![]() A Friday and Saturday typically have no theme. A Thursday has a theme that no one has seen before, a possible low word count, a little more abstract. A Wednesday puzzle is themed, so may be tricky because it has a few uncommon words holding it together. A Tuesday puzzle is a Monday puzzle with one or two uncommon answers. That’s a failure.” And he has calibrated his difficulty to accommodate the seemingly arcane continuum of Monday to Sunday puzzles in the Times. You want the puzzle to be clever but you don’t want the solver to say this constructor is a total asshole. Learning how to negotiate the delicate pas de deux between creator and solver, Quigley now balances on the razor’s edge between pleasure and pain. He has published around 30 crossword books, including 2012’s Sex, Drugs and Rock ’n’ Roll Crosswords, and has, over the years, created more than 1,500 puzzles. Now he plays in the Boston Typewriter Orchestra. And along the way, Quigley became something of a crossword celebrity. He used the stuff of his everyday life, as a twentysomething living in Boston, as clues for his puzzles: beer, bands, and the Bosox made frequent cameos. “Even in kindergarten, when we were supposed to draw pictures, I just drew intricate mazes.” Attracted by the formal elegance and rigorous structural demands of crosswords, Quigley attached himself to the confessional New Wavers of the puzzle world. “I guess I’ve always been a puzzle person,” says Quigley, who quit a progression of jobs to puzzle full-time in 2001. It was a feat virtually unheard of for a 22-year-old newbie. In the summer of 1996, three were published in The New York Times. Working first with paper and pencil, much the same way the first crossword puzzle was created in 1913, Quigley submitted puzzles to Shortz. “When Will came on board, I knew it was something special,” he says. “Every page felt like a revelation, like, wait, you can do that with a word?” And when Shortz ascended the crossword throne as The New York Times puzzle editor in 1993, Quigley, who had thus far only been a solver, pounced. Quirky and creative, the puzzles soon enchanted young Quigley. Chief among them was a young man named Will Shortz, who was an editor of Games magazine, a clever magazine filled with hidden clues, fake ads, and crossword puzzles. But ever since Maleska died in 1993, a wave of new creators was pushing the envelope, striving to make crosswords a living, breathing art form. Maleska, the conservative editor of The New York Times crossword puzzle who viewed himself as the last defence against slang in the grid. Much of this reticence was thanks to Eugene T. Not long ago the idea that a crossword could use slang or even references to contemporary culture was anathema. He’s a man unafraid of a Game of Thrones reference for Oona, long a bugaboo of crosswordese whose only clue for decades was Charlie Chaplin’s wife. “I make difficult up-to-date current puzzles for a younger generation,” explains Quigley of his work. Chances are the puzzles that have brought some of the broadest smiles to young puzzlers are those of Brendan Emmett Quigley, a crossword savant who is the sixth-most-published puzzle constructor in The New York Times under its current section editor.ĭapper yet bookish, with an owlish demeanour and a wicked-keen sense of humour, Quigley has created puzzles not only for the Times, but also for The Wall Street Journal and The Chronicle of Higher Education, and regularly for the American Values Club crossword, along with custom puzzles for the bands the Decemberists and Phish. Some puzzles are breathtakingly elegant, some are sadistically clever. Who is the man behind the clues? Is it an ogre?Įnshrined behind the mesh of lines, the small black squares-called cheaters-and the cryptic clues is often an unusually strong personality. But rarely will he pause to consider the man behind the grid. He may even ask for help from a friend, or a friend named Google. Drumming his fingers, our puzzler might mull over “a four-letter word for “green beastie” for hours. Since the paper began publishing a crossword in 1942, it has been the highest form the crossword can take. The world may be in disarray but he is alone with The New York Times crossword puzzle, a grid of answers to clues divided equally into across and down that will test his mental mettle and engulf his morning. Brandishing a pencil, a pen if he is confident, a puzzler turns to the Arts & Leisure section of The New York Times, scans the page, finds his quarry, and settles in for a fight. ![]() ![]() Some syllables will be mashed together, such that "naive" can be one syllable (" elision") or two (" hiatus"). In speaking of "syllables" we'll often use the speaker's definition rather than the dictionary's. We'll be counting either stresses or, mostly, patterns of stressed and unstressed syllables called "feet". Indeed, it can be taught to squirrels and summed up in four words: How difficult is this to learn? Too tough for most MFAs and English graduates, it seems, but in truth, not vexing at all. Scansion is "the metrical analysis of verse". So iambic pentameter describes poetry written in a ten-line, alternating stress structure."There is no escape from metre there is only mastery." Pentameter indicates there are ten syllables in the line. Iambic means to have two syllables, one stressed and one unstressed. Meter defines the number of feet in a single line of poetry.
![]() It has a curb action on the horse, and encourages the horse to lower its head when pressure is put on the reins. It should not be confused with a double bit as a weymouth bit has got double reins with it.Ī kimblewick bit is a stronger type bit generally used for trail riding on stronger horses, in showjumping classes and crosscountry. It is made up of a curb bit and a snaffle bit. The larger rings with the straight stick on the end of the bit makes sure that the bit always stays in the horse's mouth when turning.Ī Pelham bit is also a stronger bit in the english horse riding world and is regurarly used in showjumping and crosscountry (not allowed in dressage). ![]() Because of this it is a great bit again to use on younger horses where turning still needs some fine tuning. The D Ring has got slighlty larger rings than a normal snaffle loose ring bit. Gag bits should therefore only be used for riders with soft hands and not for beginners.ĭ Bits are bits with rings on the end of the bit shaped like a "D". ![]() The when the reins are pulled, the cheekpieces creates an upward action of the bit in the horse's mouth - making the horse respond quicker and being more sensitive. It is also regularly used for showjumping and polo. Gag bits are a stronger bit usually used on stronger horses, or for certain disciplines such as crosscountry when extra control is required. Eggbutt bits are also seen as a softer bit, and can be more comfortable and suitable for sensitive horses as it won't pinch the horse's mouth (as loose rings sometimes can do).įull cheek bits are usually used when training young horses as it assists when turning (the longer stainless steel sticks on the end stops the bit from going into the horse's mouth). However generally when people refer to snaffle bits they refer to the single jointed loose ring snaffle.Īn eggbutt bit refers to the rings on the side being rounded (like an egg) and fixed to the actual bit with no ability of turning. In theory a snaffle bit is actually all bits that don't have a shank. A snaffle bit is usually made of stainless steel and is seen as a relatively soft bit. It is commonly used for most english riding disciplines and comes with either a single jointed or french linked mouth. The snaffle bit is one of the most common amongst horse bridle bits. 1) Snaffle Bits (french links and jointed) Click on each image to see more information about that certain bit. We have listed the most common bridle bits types below and explained their use. Different types of bits suits different horses depending on their personality, rider and discipline used for.

These keywords were added by machine and not by the authors. These can introduce sufficient aberration and deflection into the transmitted wavefront to make it very difficult to keep the transmitted beam aligned with a standard pinhole detector as it scans over the specimen. The fact that confocal transmission modes are not generally available is partly due to the fact that most biological preparations have a complex mixture of optical properties that create regions of varying refractive index (η) and absorption. ![]() This might indeed be considered surprising, since biologists have long known the advantages of observing an enormous variety of specimens (e.g., stained or unstained, preserved or living) using conventional light microscopes with their wide range of transmission modes such as brightfîeld, phase-contrast, or differential interference contrast (DIC).
