Textbooks to go the way of the dinosaurs?

Although students and teachers alike have discovered various innovations and applications for computers over the past couple of decades, the advent of the tablet-style personal computer has very recently begun to revolutionize the market in a way that no other has done. Recent advances in lightweight, portable design, memory capacity, we could only dream of just a few short years ago, and ever-increasing networks of broadband Internet connectivity are combining to create a useful and convenient multi-purpose tool for students. Tablet sales have doubled in the past year- an explosion in popularity that even very optimistic projections for the product failed to predict.

While I don’t think anyone expects tablets to completely replace desktop or laptop computers (although a recent Nielsen survey did find that over 75% of respondents were now using their tablet for tasks that they once performed on their desktop or laptop computer), their versatility is truly astounding. One huge advantage of the tablet is that it doesn’t just replace an entire backpack full of textbooks, but also provides multimedia enhanced continuously-updated content that textbook authors could never even imagine. Whereas paper textbooks may direct student’s attention to further information and examples on the Internet, digital textbooks can provide videos and music to support any area of study at just the tap of a finger. For many students who do not learn effectively by simple reading text, this multimedia support provides a more integrated learning experience, which has been shown to improve retention and lead to positive learning outcomes.

Students may also use a tablet, as opposed to a laptop, for taking notes during lectures. Tablets provide the benefits of portability, instant startup and longer battery life so students don’t have to carry a power cord around and position themselves near an outlet. Students can also pull out their tablets and work on a project at anytime, anywhere on campus. And with cloud- based memory systems, students don’t have to bother with back-ups or flash drives if they want to continue work on their desktop computer or collaborate on a group project.

A further benefit of tablets, though one that is often cited as a shortcoming among users, is the limited ability to multitask. Now, it is true that developers have introduced thousands of applications to run on tablets, but tablets still simply cannot run many programs simultaneously. This may appear, on the surface, to pose a problem for the student user. However, in reality, students can perform any number of tasks on tablets…just not all of them at the same time. This may actually be good for a generation which is easily distracted by social media, online games, and other miscellaneous content on the Web.

Given the many benefits, it’s no wonder that tablets are beginning to make their way into classrooms. In fact, it would seem that the biggest factor working against this has simply been their limited availability. Given the long times of consumers who waited to get their hands on the first generation of tablets and the lag for other companies to get their tablets to market, many people are just now able to buy a tablet. Additionally, we should expect that as competition increases among developers, tablets should see the same steep price drops that we always witness among electronics. Thus, tablets should quickly become a very viable and economical alternative for savvy students.

     Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction. 

     Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta Texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. 

          The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space.  In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail

According to the passage, the highest amount of pheromone vapor is found _____
