I had a terrible experience with the Oxo mug. It was impossible to clean due to the enclosed design of the lid, and eventually accumulated way too much gunk inside for me to be comfortable using it. The lid on Contigo’s mug is fairly open and easy to clean, and the entire thing is dishwasher safe, though they also sell a model with a colored body that isn't. They sell replacement lids for $7 if you have a problem, but I've been using four of them for over a year in heavy rotation with no issues.

Contigo also makes plastic smaller containers for kids and larger water bottles (both of which are BPA-free) with the same Autoseal design.

The Lenspen’s other end, has "a special non-liquid cleaning element" that can be used for more aggressive cleaning. Wipe it over the lens and magically watch fingerprints disappear. The manufacturer explains that there’s a carbon compound under the cap that cleans lenses much like the ink in newspaper works to clean glass. It does work. It can be used many times over, as long as every time you put the cap back on and rotate it, to clean and recharge the pad.

This has become my most used cleaning tool, second only to the Giottos Rocket Blaster. And the two complement each other: while the Lenspen works to clean the glass surfaces of the lens and the camera’s lens mount, I use the Rocket to remove dust from the sensor.

Not only is my baby securely snuggled up against my body, but it is incredibly comfortable to wear. It looks to be about 20 feet of fabric that you wrap around your body and slip the baby into. No doubt based on some age-old method of carrying babies, it is by far the most comfortable and versatile carrier I've seen. Because it crosses around your body so many times in different locations, it distributes the weight of the child to a variety of places: shoulders, upper back, lower back and hips. Plus, the baby can face forwards, backwards or sideways when worn on your front, and she can be worn on your hips or back as well.

While it does require an introduction on how to put it on, once you have figured out how it works, it could not be simpler to use. The basic concept is that you create a cross of fabric on your body and slip the baby between you and the cross, with her legs hanging out between. Also, because of the criss-cross over your shoulders you can nestle the baby's head under the wrap, allowing full protection from the sun or, more importantly for the new parent, a quiet zone in which to nap, even at a bustling market. For all its simplicity this is simply the best baby carrier available.

There are several variations on this idea -- one with rings, one made of more stretchy material, one with fancy patterns -- from various manufacturers, but the basic design is all the same -- wrap the fabric around your body, slide the baby in and enjoy.

I value my garden fork because it’s also the best tool I have for aerating soil without tilling it. It’s good for lifting and moving stuff around the garden, some digging and uprooting, too. I bought mine from Seeds of Change a few years ago, recommended by a friend who’s had one for many years. It has a hearty ash handle and a head of four pointy sharp carbon steel tines. There surely are other worthy versions of this essential garden tool. I’m more than happy with this one.

RRS is big on system synergy. They are top-notch, beautifully made, perfect products. I have a BH-40 Ballhead on a Gitzo tripod as my main rig and a BH-25 on a Gitzo Traveler for an ultralight rig, perfect for backpacking. Each of my cameras -- Nikon D200 and Canon G9 -- has an RRS L-plate, which makes for a quick and solid connection atop both tripods, either in landscape or portrait mode.

Of the two ballheads, the BH-25 is my favorite for its super compactness. When I’m traveling or backpacking, I need a lightweight, minimal setup. The BH-25 paired with Gitzo’s Traveler is it.

I’ve been using the RRS products for about five years now, and I have to admit that part of the appeal is simply the joy of using perfectly made gear. Sometimes the tools can inspire us.

VRBO.com is an excellent means of finding reasonably priced accommodations, in the U.S. and abroad, that are often larger and more comfortable than hotel rooms, at a lower price. I’ve used it to find great short-term vacation rentals in California, Michigan and Florida. Making arrangements with the homeowners or property managers is easily handled through e-mail, and a deposit is usually required. You do have to clean up after yourself a little more than you would in a hotel room, but the savings and access to a city’s residential neighborhoods rather than its commercial districts make it a worthwhile exchange.

Firstly, its modular design is fantastic. It allows prototyping of fixtures, stands, bases and many other items we need to build for in-house use or bring to market very quickly. The number of accessories available is mind boggling. They have wheels, handles, latches, panels, leveling feet, linear slides, hinges and many more components. You can build some pretty slick items and it all just bolts together with a few simple hand tools. The finished product looks very professional, as all of the individual components are designed to work together.

All components are pre-finished. Our in-house fabricated and/or machined assemblies require outside processing (anodizing, cadmium plating, painting or powder coating), which means additional time and cost. With the 80/20, all structural extrusions and components already come painted, powder coated or anodized -- simply assemble and ship.

While 80/20 certainly will find more applications in an industrial environment, where the cost is also offset by the utility, the possibilities for home use are limited only by your imagination. You could build things such as a work bench, bicycle storage system, cabinets, stands or many other home items that will likely last a lifetime.

As with anything, 80/20 has its limitations but they are far outweighed by its capabilities. I have discovered zero fault with this product. Many of our products require very large, product-specific and engineered weldments and machined assemblies. The 80/20 will never fulfill all of our needs, but for the smaller systems we frequently design and build this "Industrial Erector Set" is superb.

The square applicator tip is supposed to make finishing the surface easier, and in fact it worked well. Although a wet finger did an equally nice job. Water is key to patching mortar, and with this stuff a wet sponge was extra helpful not only for smoothing the mortar as it cured but for wiping excess off the face of the bricks.

The 10-ounce tube cost me about $4; still a premium over dry mix. (It’s also available in a 5.5-ounce hand-squeezable size.) But for the handful of single-brick-sized repairs I needed to make, I was very thankful to avoid the setup and cleanup that mortar mix would have required. Not to mention the hassle of effectively getting the mortar from my unskilled hands into the open joints.

It is neither practical nor advisable to use Quikrete Mortar Repair to cover a large area of wall. The acrylic isn’t designed for structural tuck pointing so much as it is intended to fill in the gaps and keep water out—which is crucial if you want your brick wall to last a long time.

The Forschner Victorinox is a hybrid of a thin Japanese blade with its 15 degree edge (western knives have a 20 degree edge) but with the longer, broader blade of European knives. It is lightweight, nicely balanced, and lethally sharp. It has a comfortable very grippy handle that won't slip even when wet. We have 5 cooks at our household and this is the knife they all grab first. It may not be as super great as the chef knives previously reviewed, but for the $27 price it can't be beat.

I ride in different ways at different times. Slow, less slow, with groceries, out to dinner at a nice restaurant, for a three-hour stretch or for a quick 15 minutes away from my computer. It's been my experience that the longer I spend on a ride, and the harder I'm exerting myself, the more I appreciate highly technical clothing, commonly referred to as Lycra or a pro kit. The skintight stuff. The contoured, articulated padding (or chamois) in high-end cycling shorts by makers such as Pearl Izumi, Castelli and Assos, can go a long way toward increasing comfort for those who ride road and mountain bikes for hours at a time.

However, a lot of people don't like the look of Lycra, and not everyone can get away with skintight bike clothing. And not everyone needs to. Some riders like to have padded shorts, but also to appear civil when they dismount their bikes and enter a business or their office for the day's work. There are plenty of padded shorts intended to be worn under regular clothing, but I've found them to be generally flawed. They're designed as scaled-down versions of the aforementioned Lycra style and are uncomfortably underventilated.

Andiamo's garment design approaches the problem from the opposite, um, end. It's lightweight underwear, with a pad added. I wouldn't attempt a century in these, or even half that, but I've found them excellent for commutes, errands and other plainclothes spins, less likely to make me miserable if I don't get a chance to change as soon as I'm off my bike. They're more breathable and lightweight than anything similar I've tried.

It's an excellent compact umbrella, but the trade-off for its extreme portability is a too-small handle. The minimal size of the X1 leaves little room for a proper handle, and therefore the design incorporates a shallow cup into which the canopy tips slot when the umbrella is folded. The cup is about an inch and a half in diameter — too small and shallow to offer much purchase in windy weather.

This makes using the wrist-loop (which, to its credit, is strong and firmly attached to the cup) a must. I hold the cup low in my hand and grip the tube above it like a golf club — thumb pressed on the tube, with the first two fingers wrapped around it. This isn’t so comfortable for prolonged use, but it’s enough to hold the umbrella steady in gusty weather, although not steady enough to stop it being blown about a bit.

I have used the smart money clip for six years. No more wallet, just the five cards I use all the time, and a little bit of cash if someone doesn’t want to take my MasterCard. It keeps my pockets free, and I have never seen anything else like it.

The most care they require is a coat or two of Sno-Seal every season. Unlike synthetic gloves, they aren't fazed by heat and flame. I've found that the Kinco 901 gloves paired with some cheap silk liners is enough to keep my hands warm until it gets below 5F or so.

The tower is at the center of a field of heliostats (mirrors that track the movement of the Sun) that focus the bright Spanish sunlight onto a receiver near the tower's top. The reflected sunlight is so intense that water vapor and dust in the air glow white. All that's needed to complete the scene is a maniacal James Bond villain atop the tower.

This tower is at the center of the Solucar PS10 power station. At the top of the tower is a solar receiver that is heated by sunlight to create saturated steam at 257°C. The steam is then used to drive a turbine that generates electricity. Make sure you're wearing sunglasses when you look up to the top; the tower's brilliant white glow is very intense.

Taipei 101, Taipei, Taiwan
The 660-Tonne Golden Ball

The Taipei 101 is the tallest occupied building in the world, with 101 floors overlooking Taipei's business district. But Taipei is prone to both typhoons and earthquakes, so the skyscraper contains a 660-tonne, gold-colored pendulum near the top to prevent the building from swaying and vibrating. It is the largest and heaviest such pendulum in the world.

Many skyscrapers contain such devices, called tuned mass dampers, for the same purpose, but the Taipei 101 pendulum is unusual because it is on public view. It hangs between the 87th and 91st floors, and there are public viewing areas on the 88th and 89th floors. It's even visible from the restaurant and bar. Two other tuned mass dampers, located in the building's pinnacle are not on display and are tiny by comparison: they weigh only 6 tonnes each.

The ball is made of forty-one 12.5-centimeter steel plates welded together for a total size of 5.5 meters. It is attached to the building by eight steel cables, each capable of supporting the ball's entire weight. In normal use the ball can move up to 35 centimeters in any direction and cuts building vibration by 40%. In a major typhoon, the ball is designed to move up to 1.5 meters; hydraulic bumpers below the ball absorb its energy and prevent it from moving too far.

When the building sways in one direction, the ball opposes the movement by swinging the opposite way. The movement of the ball pushes (and pulls) on the hydraulic bumpers and causes them to heat up, absorbing the energy from the motion of the building. The pendulum is tuned by adjusting the length of the cables holding it. By changing the period of the pendulum (the time it takes to swing back and forth), it can be tuned to match the motion of the building.

Nevada Test Site, NV

At the Nevada Test Site, more than 1,000 nuclear explosions were set off between 1951 and 1992. The site contains over 3,600 square kilometers of dry lake beds and mountains, about 100 kilometers northwest of Las Vegas. Once a month, the U.S. Department of Energy provides a free, day-long tour of the Nevada Test Site's bomb craters, ground zeros, and test paraphernalia.

The tour covers around 400 kilometers of the nuclear explosion-pockmarked landscape: of the 1,021 nuclear explosions at the Nevada Test Site, only 126 occurred above ground; the rest were underground tests that left the site cratered. The largest crater of all, the Sedan Crater, is the highlight of the tour. It's almost 400 meters wide and 100 meters deep.

This book is unlike any other on writing I’ve seen. It is not about basic rules. It is not a standardized style guide to be used as a reference manual. Artful Sentences is divided up into 14 chapters; each chapter covers a different concept related to syntax. Tufte provides her analysis first and then follows with an example. Sometimes she quotes an entire paragraph to demonstrate the impact the chosen sentence has within its original context.

Don’t let dry chapter titles such as “Short Sentences,” “Noun Phrases,” “Prepositions,” etc., deter you; the content is highly academic and at times dense, but it's a pleasurable read in proper doses. I prefer to explore Artful Sentences in short spurts. The sample sentences often catch my attention first and then I dig in to see what Tufte says about them. (You can also use the index to choose a favorite author and then search out his/her quotes.) I process what I’ve read and return to the book at a later time -- opening it up to any one of its 14 chapters and starting again. Reading Tufte’s book gives me the immediate pleasure of saying, “Damn, that’s a good sentence!” often followed by, “Now how do I create one of my own?” The experience is similar to learning about visual art or playing music.

These farmers produce valuable goods, of course; but they also conserve soil, they conserve water, they conserve wildlife, they conserve open space, they conserve scenery.
Wendell Berry, Citizenship Papers, 170

Syntactic Symbolism
Another repetition of prepositional phrases, here artfully doubled, divides a sentence’s spaces into spaces into spaces. This helps to imitate and dramatize an effective simile emphasized by its syntax as a fragment:

Space is all one space and thought is all one thought, but my mind divides its spaces into spaces into spaces and thoughts into thoughts into thoughts. Like a large condominium. Occasionally I think about the one Space and the one Thought, but usually I don’t. Usually I think about my condominium.
Andy Warhol, The Philosophy of Andy Warhol, 143

Left-Branching Sentences
In many successful left-branching sentences, there is a temporal or logical development of the expressed idea that invites the delayed disclosure of the left-branching arrangement. The material that concludes the sentence makes an almost inevitable point:

The afternoon after the night at the tavern, while O's were being taken out of books and out of signs, so that the cw jumped over the mn, and the dish ran away with the spn, and the clockshop became a clckshp, the toymaker a tymaker, Black issued new searching orders.
James Thurber, The Wonderful O, 9-10
