時々急に不安になるときはないですか? Do you ever suddenly feel anxious? 私は,今日がまさにその日です. Today is exactly one of those days for me. 不安はどこからくるのでしょうか. Where does anxiety come from? バイオリズムだとわかっていても,このような気持ちは好きじゃないです. Even though I know it’s just biorhythm, I don’t like this kind of feeling. 好きになれればよいのですが. I wish I could learn to like it. 私は,バイオリズムのような,お話は当時まで全く興味がなかったです. I had absolutely no interest in topics like biorhythm back then. どちらかというと女性がそういうことに興味があり,血液うらないとか,星座占いを女性がすきです. If anything, it seemed more like something women were interested in—things like blood type fortune-telling or horoscope readings that women tend to like. ただ,バイオリズムは,このカレンダーを信じるわけではないですが,必ずあると思います. However, while I don’t necessarily believe in the accuracy of this kind of calendar, I do think biorhythms definitely exist. 女性は,生理があり,そのリズムで体調や気持ちがかわります. Women have menstrual cycles, and their physical condition and emotions change with that rhythm. このような生体のリズムは男性にも,女性にもあるとおもうんですね. I believe that such biological rhythms exist in both men and women. 最近は,リズムがきたと,諦めてなにもしません. These days, when the rhythm comes, I just accept it and do nothing about it. なぜなら,何もしても,気持ちは変わらないです. Because no matter what I do, my feelings don’t change. 一般的な出来事ですと,変化はないですね. With ordinary events, there’s no noticeable change. 不安から違うところに集中力を向かわせることが,このリズムを乗り越える唯一の方法ですね. Redirecting my focus away from anxiety is the only way to overcome this rhythm. |

Unlocking Word Meanings
Read the following words/expressions found in today’s article.
- drone / droʊn / (n.) – a type of small aircraft that can fly without a pilot and can be controlled from the ground
Example:
There are companies using drones to deliver medicine in remote locations.
- experimentation / ɪkˌspɛr ə mɛnˈteɪ ʃən / (n.) – the process of testing methods, strategies, and products to determine its effects, especially if it’s good and effective
Example:
It will take many years of experimentation before the car company can release the first flying car.
- centralized / ˈsɛn trəˌlaɪzd / (adj.) – under the control of a single main system or authority
Example:
The company has a centralized system to manage all its customer information in one place.
- scale up (something) / skeɪl ʌp / (phrasal v.) – to increase something’s size, quantity, or scope
Example:
Factories scale up production of their items before the holiday shopping season.
- onboard / ˈɒnˈbɔrd / (adj.) – being carried on a vehicle or happening on a vehicle
Example:
The robot uses onboard sensors to detect obstacles and move around safely.

Moving in a dense cloud, like a flock of birds in flight, 100 drones maneuver through the night sky in an open field just outside Hungary’s capital. It’s the result of more than a decade of research and experimentation that scientists believe could change the future of unmanned flight.
The behavior of the swarm, made up of autonomous drones that make their own decisions without pre-programming or centralized control, is guided by research conducted by Hungarian scientists at Eötvös Loránd University (ELTE) in Budapest on the collective movements of creatures from the natural world.
“We don’t scale up our systems from designing one single drone and then having multiple ones,” says Gábor Vásárhelyi, a senior researcher at the university. “But we start this whole thing with the mindset of collective motion and collective behavior.”
In recent years, drones have become a common sight in the sky: Companies like Amazon and FedEx have launched drone delivery services, hobbyists use them for aerial photography, and groups of more than 1,000 drones have been programmed to deliver large-scale light shows.
But the scientists at ELTE’s Department of Biological Physics have developed new models based on the behavior of animals to allow a large number of drones to travel autonomously and react in real-time to their environment and each other as they execute individual routes and tasks.
“This is the level of what we call decentralization or decentralized systems. After the drones are told what to do, we can switch off the ground control station, we can burn it, or whatever, throw it away,” says Vásárhelyi. “The drones will be able to do what they have to do just by communicating to each other.”
Using data the researchers gathered by monitoring the flight of pigeons, the movements of wild horses on the Great Hungarian Plain, and other animal behavior, they developed an algorithm that allows the drones to make onboard, autonomous decisions and safely mitigate conflicts to avoid collisions.
Digital models in three dimensions have convinced the researchers that the algorithm can successfully support 5,000 drones flying together autonomously.

Viewpoint Discussion
Enjoy a discussion with your tutor.
Discussion A
- How would you feel if hundreds of drones flew over you in public? Should there be limits on where and how many drones can fly at a time? Why or why not? Discuss.
- Drones can take photos and videos while they’re flying. Does this concern you? What else should people be concerned about with many drones in the sky? What measures should the government implement to ease the public’s concerns regarding the use of drones? Discuss.
Discussion B
- In ELTE’s experimentation, drones can make decisions without needing human instructions. How much do you trust technology to operate autonomously? What tasks would you never want an autonomous device to do for you? Why? Discuss.
- What autonomous devices do you have at home that you can confidently use with no issues (ex. robot vacuum, AI-powered washing machine)? How satisfied are you with the performance of these autonomous devices? Discuss.
