When you drive the ball at its natural frequency, the ball’s oscillations increase in amplitude with each oscillation for as long as you drive it. As you increase the frequency at which you move your finger up and down, the ball will respond by oscillating with increasing amplitude. If you move your finger up and down slowly, the ball will follow along without bouncing much on its own. At first you hold your finger steady, and the ball bounces up and down with a small amount of damping. Most of us have played with toys where an object bobs up and down on an elastic band, something like the paddle ball suspended from a finger in Figure 14.18. The phenomenon of driving a system with a frequency equal to its natural frequency is called resonance, and a system being driven at its natural frequency is said to resonate. ![]() The natural frequency is the frequency at which a system would oscillate if there were no driving and no damping force. Over time the energy dissipates, and the amplitude gradually reduces to zero- this is called damping. This is a good example of the fact that objects-in this case, piano strings-can be forced to oscillate but oscillate best at their natural frequency.Ī driving force (such as your voice in the example) puts energy into a system at a certain frequency, which is not necessarily the same as the natural frequency of the system. It will sing the same note back at you-the strings that have the same frequencies as your voice, are resonating in response to the forces from the sound waves that you sent to them. ![]() Sit in front of a piano sometime and sing a loud brief note at it while pushing down on the sustain pedal. Before the start of this section, it would be useful to review the properties of sound waves and how they are related to each other, standing waves, superposition and interference of waves.

Lu is an assistant professor of biomedical engineering at GW. “The tool developed in our work has great potential to address unmet needs in many programs of fundamental and translational cardiac research.”Įfimov is a professor of biomedical engineering at Northwestern’s McCormick School of Engineering and professor of medicine at Northwestern University Feinberg School of Medicine. “Many deaths that occur following heart surgery or a heart attack could be prevented if doctors had better tools to monitor and treat patients in the delicate weeks and months after these events take place,” added GW’s Luyao Lu, who co-led the work with Efimov. Our transient electronic device can map electrical activity from numerous locations on the atria and then deliver electrical stimuli from many locations to stop atrial fibrillation as soon as it starts.” We hope our new device can close this gap in technology. “Current post-surgical monitoring and treatment of these complications require more sophisticated technology than currently available. “Several serious complications, including atrial fibrillation and heart block, can follow cardiac surgeries or catheter-based therapies,” said Northwestern’s Igor Efimov, an experimental cardiologist who co-led the study. The research was published July 5 in the journal Science Advances. The device also is highly transparent, allowing physicians to observe specific heart regions to make a diagnosis or provide a treatment. Not only can it be placed on various sections of the heart, the device also continuously streams information to physicians, so they can remotely monitor a patient’s heart in real time. ![]() And, after the device is no longer needed, it harmlessly dissolves inside the body, bypassing the need for extraction.Ībout the size of a postage stamp, the soft, flexible device uses an array of sensors and actuators to perform more complicated investigations than traditional devices, such as pacemakers, can accomplish. To help prevent those deaths, researchers at Northwestern and George Washington (GW) universities have developed a new device to monitor and treat heart disease and dysfunction in the days, weeks or months following such events. Nearly 700,000 people in the United States die from heart disease every year, and one-third of those deaths result from complications in the first weeks or months following a traumatic heart-related event. ![]() But be sure to sign up for their email list to get any potential shipping discounts or free shipping offers during special sale events throughout the year.

Understanding the Elements of PoetryĪs we explore how to write a poem step by step, these three major literary elements of poetry should sit in the back of your mind: These devices-rhyme, meter, and line breaks-are just a few of the essential elements of poetry, which we’ll explore in more depth now. Poetry has a heightened emphasis on the musicality of language itself: its sounds and rhythms, and the feelings they carry. Poetry further accentuates its use of language through rhyme and meter. Rather than letting the text break at the end of the page (as prose does), verse emphasizes language through line breaks. This means that it uses line breaks, alongside rhythm or meter, to convey something to the reader. Most poetry is written in verse, rather than prose. The elements of poetry help it to powerfully impact the reader in only a few words. ![]() Together, these elements of poetry help it to powerfully impact the reader in only a few words. Poetry is not like other kinds of writing: it has its own unique forms, tools, and principles. In poetry, every single word carries maximum impact. So poetry isn’t the place to be filling in long backstories or doing leisurely scene-setting. “Prose: words in their best order poetry: the best words in the best order.” Here’s a famous quote that enforces that distinction: Unlike longer prose writing (such as a short story, memoir, or novel), poetry needs to impact the reader in the richest and most condensed way possible. Poetry is Language at its Richest and Most Condensed Here’s a contemporary poem that, despite its simplicity (or perhaps because of its simplicity), conveys heartfelt emotion. In other words, a poem should make the reader feel something-not by telling them what to feel, but by evoking feeling directly. Poetry is a lyrical, emotive method of self-expression, using the elements of poetry to highlight feelings and ideas.Ī poem should make the reader feel something. Some poetry may be this way, but in reality poetry isn’t about being obscure or confusing. People sometimes imagine poetry as stuffy, abstract, and difficult to understand.
