The ability to think creatively is not a gift everyone possesses naturally, so it must be developed as a skill. Here are some tips to help you develop creative and critical thinking abilities.
Step outside your comfort zone
Stepping outside of your comfort zone is an easy way to expand your creative and critical thinking skills. This can mean reading a book or an article that is completely unrelated to any previous studies, or even having a difficult conversation with someone you're close to. 1.. We all grow from discomfort.
Stay healthy
Your mind is in the best shape when your body is. Coupling exercise with a healthy diet can clear the mind and allow for creativity. 2.. Some people are easily distracted by a messy office or a dark room. Most people are the most awake when they are in clean, healthy, and organized environments.
3..
This is a common technique used by journalists and writers suffering from writer's block. It's an easy tool to get the creative juices flowing. Open up a laptop, or grab a notebook and pen, and just start writing. Just let your mind take you wherever it wants to go. 4..
Take a breather
Everyone may reach points where they get stuck on an idea and can't get past it. Don't let this discourage you, and don't blame yourself. That sort of thinking will make you disheartened and distracted, which will only make you even more frustrated. 5.. Co outside for some fresh air, take a walk, eat a meal, or call a friend. Distraction, in moderation, can be very rewarding.
A.Write freely
B.Keep an open mind
C.Instead, take a short break
D.Keep your spirits high at work and even during the holidays
E.This is a great way to explore your thoughts and expand your creativity
F.Your work environment can also greatly affect the way the brain functions
G.Anything making you a bit uncomfortable probably benefits you more than it harms you
One of a doctors’ most valuable tools is his nose. Since ancient times, medics have relied on their sense of smell to help them work out what is wrong with their patients. Fruity odors (气味) on the breath, for example, let them monitor the condition of diabetics (糖尿病病人).
But doctors can, as it were, smell only what they can smell—and many compounds characteristic of disease are odorless. To deal with this limitation, Hossam Haick, a chemical engineer at the Technion Israel Institute of Technology in Haifa, has developed a device which, he claims, can do work that the human nose cannot.
The idea behind Dr. Haick’s invention is not new. Many diagnostic “breathalysers” already exist, and sniffer dogs, too, can be trained to detect illnesses such as cancer. Most of these approaches, though, are disease-specific. Dr. Haick wanted to generalize the process.
As he describes in ACS Nano, he and his colleagues created a series of electrodes made of carbon nanotubes (纳米碳管). Each of these had one of 20 organic films laid over it. Each film was sensitive to one of a score of compounds known to be found on the breath of patients suffering from a range of 17 illnesses, including Parkinson’s disease, multiple sclerosis, and bladder cancer. When a film reacted, its electrical resistance changed in a predictable manner. The combined changes produced an electrical fingerprint that would be diagnostic of the disease a patient was suffering from.
To test their invention, Dr. Haick and his colleagues collected 2,808 breath samples from 1,404 patients who were suffering from at least one of the diseases. Its success varied. It could distinguish between samples from patients suffering from gastric cancer and bladder cancer only 64% of the time. At distinguishing lung cancer from head and neck cancer it was, though, 100% successful. Overall, it got things right 86% of the time. Not perfect, but a useful aid to a doctor planning to conduct further investigations. And this is only the first model. Slightly adjusted, its success rate would be expected to improve.
