2 . In the annals of human history, few subjects have generated as much excitement, debate, and guess as artificial intelligence (AI). This revolutionary technology, which enables machines to perform tasks that once required human intelligence, has the potential to transform every part of our society, from healthcare and finance to transportation and entertainment.

At its heart, AI is all about data. Massive amounts of data are fed into algorithms that learn from this data, allowing them to make predictions, recognize patterns, and even make decisions. This “machine learning” is the driving force behind many of the AI applications we see today, from virtual assistants like Siri and Alexa to more advanced systems like IBM’s Watson, which can analyze vast amounts of information to assist doctors in diagnosing diseases.

The transformative potential of AI is undeniable. In the medical field, for instance, AI can assist in early detection of diseases, predict patient outcomes, and even suggest treatment options. In finance, algorithms can predict stock market trends, and provide personalized financial advice. In transportation, self-driving cars equipped with AI systems promise to reduce accidents, ease traffic jams, and transform urban landscapes.

However, with great potential comes great responsibility. The rise of AI has caused debates about is ethical implications (道德含义). The machines are only as good as the data they are fed, and there’s a growing concern about biases (偏见) being built into AI systems. For instance, facial recognition technologies, used in everything from unlocking phones to police monitoring cameras, have come under check for misidentifying individuals based on race or gender.

Moreover, the widespread adoption of AI could lead to significant job displacement. While new roles and industries might emerge as a result of AI, it is not sure that these will pay off the jobs lost. This could increase income inequalities and causes difficulties to social systems.

Another major concern is the “black box” nature of AI. Many AI systems operate in ways that even their creators don’t fully understand. This can be problematic, especially in critical applications like healthcare or criminal justice where understanding the logic behind a decision is important.

Then there’s the potential for AI to be weaponized. In the hands of evil actors, AI could be used to spread misinformation, control public opinion, or even engage in internet warfare. The global community must come together to set standards and regulations to prevent such misuse.

On the brighter side, many experts believe that by setting the right frameworks and investing in education and retraining, we can use the power of AI for the greater good. By fostering (促进) a culture of continuous learning and staying abreast (并排的，并肩的) of technological advancements, society can benefit from the promise of AI while avoiding its potential dangers.

In conclusion, artificial intelligence stands as one of the most profound inventions of our time. While it offers vast opportunities, it also poses significant challenges that we, as a society, must welcome. As we stand at this technological crossroads, our choices will determine whether AI serves as a benefit or a harm for humanity.

3 . Frozen in time, a 125-million-year-old mammal attacking a dinosaur. A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.

Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.

Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.

In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past mass extinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.

Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.

Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.

Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.

4 . For many American high school seniors and their families, May 1 is “National College Decision Day,” when students make a decision about their academic future.     1     According to a recent survey, more than half of Americans don’t even think college is worth the cost. This is upsetting, as completing college is as important as ever.

    2     Even in today’s competitive labor market, college graduates find work much easier and tend to command significantly higher incomes. The unemployment rate for those with a bachelor’s degree or greater is currently half that of those with a high school degree. This college income advantage is due to technological advances like the personal computer and the Internet, which have caused a huge demand for skilled workers. The rapid advances today in automation and artificial intelligence will further increase the need for a highly skilled workforce.     3    

It is understandable why many students and families suspect that college is no longer “worth it.” College tuition has been rising for years, and many students fear being burdened with loans after graduation. But in fact, the net price of a four-year college, which is what students pay after financial aid, has been falling since 2018 and is now lower than it was in 2006.     4     In other words, the investment paid off.

To make smart decisions about where to go and what to study, students and parents can make use of resources available today to make informed choices.     5     With these resources, students can gain a reasonable picture of what their future holds down each potential path.

5 . If the great dinosaurs hadn’t gone extinct, would they have dominated Earth today? There has been a debate about this possibility for decades. Recently two analyses have put the surprising cognitive (认知) abilities of dinosaurs — and their potential limitations — in a new light.

In one study, Suzana Herculano-Houzel at Vanderbilt University calculated the likely number of neurons (神经细胞) in dinosaurs’ pallium, a brain structure that is responsible for advanced cognitive functions. Research suggests that it is the number of neurons in these areas, rather than the brain size, that indicates an animal’s cognitive potential. For example, despite having a very small head, birds have more densely packed brain cells than many mammals (哺乳动物) and so can possess roughly as many neurons as monkeys. The result is that some birds show great cognitive abilities, comparable to the smartest non-human mammals. And it is precisely birds, being the only surviving lineage (宗系) of dinosaurs, that are Herculano-Houzel’s foundation. By comparing the relationship between brain size, number of neurons and body size in numerous existing birds and available fossils of dinosaurs, Herculano-Houzel concludes that a large dinosaur such as T. rex could have housed two billion to three billion neurons in its pallium. If so, dinosaurs could have had the capacity for tool use and planning for the future.

But neurons’ number may not be enough. For intelligence, brain architecture also matters. And this could be the weakness of dinosaurs, argues Anton Reiner from the University of Tennessee. Over 350 million years of separate evolution, mammals and dinosaurs found two rather different ways to organize cognitive functions. The mammalian neurons are organized in a relatively thin layer formed by compact columns. In each column, different parts can communicate with one another over short distances. In contrast, in the dinosaurs that survive today, namely birds, the organization is less compact. According to Reiner, expanding brain capabilities beyond a certain point could make the structure far more complex and less efficient than it is in humans. If this were the case, an increase in brain size would correspond to a greater distance between different parts of the brain, slowing down their communication.

The issue remains open to debate. Herculano-Houzel and Reiner each published a paper with rejections to the other’s argument. Meanwhile, other scientists have entered the fight. For example, neurobiologist Giorgio Vallortigara assumes that speed in transmitting information between networks of neurons is probably one of dinosaurs’ strengths.

Whatever the truth is, understanding how and if brain architecture imposes limits on the development of cognition could reveal much about the evolution of abilities and behaviors of various animals. Also, this debate may tell us more about our own species than about dinosaurs.

6 . “Find your passion!” is an appeal well-intended and meant to inspire. But is it good advice?

“Finding” a passion implies that it already exists and is simply waiting to be discovered. Unfortunately, this idea doesn’t square with what science tells us. Instead, passions are developed. They often begin with a spark (火花) of curiosity caused by something in one’s environment, such as a fascinating physics lecture. Through a process involving repeated engagement and-positive experiences, people can come to personally value that content or activity and internalize it. What was at first interesting becomes an interest. If these qualities continue to intensify, a passion can emerge.

Actually, assuming passion as inborn tend to cause people to be less open, less courageous in the face of challenges and less creative in pursuit of new interests. Thus, encouraging people to “find” their passion may cause them to eventually believe that interests and passions are unchangeable. People who think this have a fixed mindset of interest. By contrast, some people, whom we refer to as having a growth mindset of interest, view their interests and passions as developed.

People with a fixed mindset of interest, for example, may fall into the trap of thinking, “If I have already found my passion, why keep exploring?” In recent studies, after engaging in a new science task, arts students with a fixed mindset expressed less interest in a scientific topic than arts students with a growth mindset. Meanwhile, science students with a fixed mindset responded similarly to an art-related task. For those with a growth mindset, having a strong pre-existing interest in the arts or sciences did not get in the way of them viewing a new area as interesting.

Worse still, people with a fixed mindset of interest tend to expect their passions to provide limitless motivation, such that their favorite topics should never feel too difficult or demanding. Such a mindset can also limit creativity and innovation. If people believe they are restricted to only a few inborn interests and, in consequence, do not explore other areas, they may miss seeing important connections across different fields. That loss is especially unfortunate considering how leaders at innovative companies have long prized problem-solving that draw ideas from diverse disciplines.

Of course, not every activity will become a burning passion. But a growth mindset of interest will help you remain open and curious. The old saying “find something you love to do, and you’ll never have to work a day in your life” needs to be updated.

7 . As higher education leaders dive deeper into the conversation on Digital Transformation and Education 4.0, they are also learning how to incorporate the Digital Twins realm concept into their curricula, because Digital Twin technology can serve the university of the future.

A Digital Twin is a virtual representation of a real object or system which is updated from real-time data and uses machine learning, simulation (模拟), and reasoning to help decision-making. In other words, a Digital Twin can create a highly complex virtual model which is the exact replica of a physical thing. Connected sensors on a smart campus can collect data in real time. This data is used to create a map onto the virtual model, thus creating a Digital Twin of a campus. When school administrators look at the Digital Twin, they can see crucial information about how the real campus is doing.

The applications for Digital Twin technology do not stop there. Students and faculty can benefit from using the technology as well. For example, hybrid classrooms have become more and more common nowadays. Digital technologies have accelerated the transition into the university of the future. Digital Twin technology, one of the trending technologies related to Industry 4.0, helps faculty create simulation models based on course requirements.

Digital Twin technology makes the ultimate immersive learning experience possible. By using a Digital Twin, students can learn highly engaging tasks which can be too dangerous, complex, or expensive for the classroom. Rather than hands-on laboratory dissection of a physical frog to learn animal science or having to wait for available human organs in the health science lah, medical students can use the virtual twin of an animal or human organs for their study.

The complexity of chemistry or microbiology requires students to be totally engaged. By using Digital Twins in a Virtual Reality simulated learning experience, faculty can achieve a maximum level of engagement helping each student learn abstract concepts in their own unique way and much faster. By running simulations, students can better explore system behavior under different conditions, understand failure and develop an understanding of system sensibilities as well as how changes in the system parameters (参数) and external disruptions make an impact on the results.

Some universities, such as Stanford and Copenhagen School of Marine Engineering, have incorporated Digital Twin technology into their teaching curricula, applying it to disciplines like architecture and engineering as they believe they are the reality of the industry. Overall, this enhances student motivation, accelerates understanding, and improves the overall learning experience. Moreover, the industry encourages universities to incorporate educational Digital Twins in automation to give students the initial understanding of tools and skills they will need in their future.

8 . In our information-driven society, shaping our worldview through the media is similar to forming an opinion about someone solely based on a picture of their foot. While the media might not deliberately deceive us, it often fails to provide a comprehensive view of reality.

Consequently, the question arises: Where, then, shall we get our information from if not from the media? Who can we trust? How about experts—people who devote their working lives to understanding their chosen slice of the world? However, even experts can fall prey to the allure of oversimplification, leading to the “single perspective instinct” that hampers(阻碍)our ability to grasp the intricacies of the world.

Simple ideas can be appealing because they offer a sense of understanding and certainty. And it is easy to take off down a slippery slope, from one attention-grabbing simple idea to a feeling that this idea beautifully explains, or is the beautiful solution for, lots of other things. The world becomes simple that way.

Yet, when we embrace a singular cause or solution for all problems, we risk oversimplifying complex issues. For instance, championing the concept of equality may lead us to view all problems through the lens of inequality and see resource distribution as the sole panacea. However, such rigidity prevents us from seeing the multidimensional nature of challenges and hinders true comprehension of reality. This “single perspective instinct” ultimately clouds our judgment and restricts our capacity to tackle complex issues effectively.

It saves a lot of time to think like this. You can have opinions and answers without having to learn about a problem from scratch and you can get on with using your brain for other tasks. But it’s not so useful if you like to understand the world. Being always in favor of or always against any particular idea makes you blind to information that doesn’t fit your perspective. This is usually a bad approach if you would like to understand reality.

Instead, constantly test your favorite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about new information that doesn’t fit, and information from other fields. And rather than talking only to people who agree with you, or collecting examples that fit your ideas, consult people who contradict you, disagree with you, and put forward different ideas as a great resource for understanding the world. I have been wrong about the world so many times. Sometimes, coming up against reality is what helps me see my mistakes, but often it is talking to, and trying to understand, someone with different ideas.

If this means you don’t have time to form so many opinions, so what? Wouldn’t you rather have few opinions that are right than many that are wrong?
