It constitutes a rare object of envy.

Sugar, alcohol and tobacco, economist Adam Smith once wrote, are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation.

Today’s consumers want beautiful handcrafted objects to wear and to have for their home environment.

Ask yourself, Would Grandma consider this food? Does it look like something that might occur in nature? It's pretty much common sense: you want to buy food, not unidentifiable foodlike objects.

Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you've visited many times before can also be signs of something going wrong.

When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected.

When the container was tipped over, sometimes an object fell out and sometimes it didn't.

Some communities have agreed to share online—geneticists, for example, post DNA sequences at the GenBank repository ( ' , 庫), and astronomers are accustomed to accessing images of galaxies and stars from, say, the Sloan Digital Sky Survey, a telescope that has observed some 500 million objects—but these remain the exception, not the rule.

Historically, scientists have objected to sharing for many reasons: it is a lot of work; until recently, good databases did not exist; grant funders were not pushing for sharing; it has been difficult to agree on standards for formatting data; and there is no agreed way to assign credit for data.

Many even think their parents are cool! Although more than a third have an object in their rooms they would like to keep secret from their parents, rarely is it anything more alarming than a diary or offcolor ( ' , 低俗的) book or CD.

But over the last couple of years, and in this one in particular, we are starting to see companies shift from what is the largest screen size, the smallest form factor or the shiniest object and more into what all of these devices do that is practical in a consumer's life.

So a heavy object, like a football player moving at a high speed, has a lot of momentum — that is, once be is moving, it is hard to change his state of motion.

Physical characteristics of moving objects help explain the dynamics of energy systems.

Not only moving objects and people but all systems have momentum.

Inertia is the resistance of objects to efforts to change their state of motion.

In physics, moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia and momentum.

If the CFL should be used for lighting a particular space, or an object within that space, the fixture must be designed to work with that lamp, and that fixture with the room.

Consider the incandescent ( ' , 白熾燈 ) bulb, an object currently hated by many environmentalists and energy-efficiency advocates.

After all, we don't speak only of objects or people as having momentum; we speak of entire systems having momentum.

Why does the author object to classifying parenting as a personal choice?

The size of the objects shown.

Boys pay more attention to moving objects than girls

Consider the incandescent (白熾燈) bulb, an object currently hated by many environmentalists and energy-efficiency advocates.

For example, when information is uploaded to a repository,a digital object identifier is assigned.

In one experiment, 145 undergraduates completed four unusual uses tasks, each requiring them to list as many uses as possible for everyday object.

So a heavy object, like a football player moving at a high speed, has a lot of momentum — that is, once he is moving, it is hard to change his state of motion.

So how do people assign traits to an object?

The knowledge we have about the object constitutes the cognitive component of an attitude.
