مرض المتعلّمين disease of the learned هو مصطلح إشتهر بالقرن الـ 18 بإنكلترا وأوروبا عمومًا. الفكرة جانت أنّ الأكاديميين والأشخاص اللي يقضون وقت طويل بالتفكير والقراءة رح يعانون من هالمرض اللي أعراضه جانت تختلف من مصدر طبي للآخر، لكن عمومًا تشمل الاكتئاب، مشاكل الظهر، العيون، والمعدة. ديفيد هيوم اشتهر بأنه جان يعاني منه من عمر الـ 19 وجان يعالجه بالنزهة ولعب الطاولي.

Disease of the learned مرض المتعلّمين

بغض النظر عن إستنتاجِ تولستوي الأخير. أنا أعتقدُ أنّ السؤال حول معنى الحياة هو سؤالٌ عقيمٌ بحدّ ذاته: ربما بدلًا من تضييع الوقت بمحاولة الإجابة عن هذا السؤال*، يمكننا أنْ نستغل منطق تولستوي ونسأل عن طبيعة الأشخاص الذين يطرحون مثل هكذا سؤال: فالأشخاص الذين يسألون عن "معنى" الحياة الإنسانية بشكل عام، هم أشخاص أُشبِعَت كل رغباتهم "الضرورية" وبالنتيجة لم يتبقَ لهم سوى غير الضروري فقط. بهذا المنطق، فالسؤال حول معنى الحياة هو في حقيقته سؤال شخصيٌ حول فائدة حياتهم هُم، وليس عن معنى الحياة الإنسانية كلِّها. باختصار: هو مشكلةٌ شخصية أُلبِسَت لباس معضلةٍ فلسفية.
إنّ مثل هكذا أسئلة هي مجرد طريقة بلاغية معقدة للتعبير عن مشكلة شخصية واحدة وبسيطة: "ماذا يجب أنْ أفعل الآن؟". مثل هكذا أشخاص يكونون بلا حاجات ملِحّة على المدى القريب، وبالنتيجة، ليس عندهم أيّ شيءٍ ضروري ليفعلوه، الأمر الذي يخلقُ لهم وقتَ فراغٍ كبيرًا لا يمكن ملؤه بأنشطةٍ بسيطة. وقتُ الفراغ هو الذي يتسائلون عن "معناه"، وليس الحياة الإنسانية. باختصار: يأسُهم يأتي من حيرتهم، وحيرتُهم تأتي من أنّ كل خيّاراتِهم "غير ضرورية" وبالنتيجة فهي غير ملحّة بما يكفي أو جذّابةٍ بما يكفي ليختاروها.
إنّ السؤال حول معنى الحياة، غالبًا ما يكون ناتجًا من حيرةِ مرءٍ لا يعرف أين وكيف يقضي وقت فراغه بعد الظهر.

*هو بالفعل مضيعةٌ للوقت من ناحية عملية، لأن عددًا لا يُحصى من الفلاسفة والمفكرين والمدارس الفكرية كلها حاولت الإجابة عنه بلا جدوى. وكما يقول تولستوي:
"If you want to be happy, be."

An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day for one year. To make this one, a 4x5 pinhole camera was set up looking north in southern New Zealand skies. The shutter was briefly opened each clear day in the afternoon at 4pm local time exposing the same photosensitized glass plate for the year spanning September 23, 2022 to September 19, 2023. On two days, the winter and summer solstices, the shutter was opened again 15 minutes after the main exposure and remained open until sunset to create the sun trails at the bottom and top of the curve. The equinox dates correspond to positions in the middle of the curve, not the crossover point. Of course, the curve itself is inverted compared to an analemma traced from the northern hemisphere. And while fall begins today at the Autumnal Equinox for the northern hemisphere, it's the Spring Equinox in the south.

Do stars always create jets as they form? No one is sure. As a gas cloud gravitationally contracts, it forms a disk that can spin too fast to continue contracting into a protostar. Theorists hypothesize that this spin can be reduced by expelling jets. This speculation coincides with known Herbig-Haro (HH) objects, young stellar objects seen to emit jets -- sometimes in spectacular fashion. Pictured is Herbig-Haro 211, a young star in formation recently imaged by the Webb Space Telescope (JWST) in infrared light and in great detail. Along with the two narrow beams of particles, red shock waves can be seen as the outflows impact existing interstellar gas. The jets of HH 221 will likely change shape as they brighten and fade over the next 100,000 years, as research into the details of star formation continues.

The sprite and tree could hardly be more different. To start, the red sprite is an unusual form of lightning, while the tree is a common plant. The sprite is far away -- high in Earth's atmosphere, while the tree is nearby -- only about a football field away. The sprite is fast -- electrons streaming up and down at near light's speed, while the tree is slow -- wood anchored to the ground. The sprite is bright -- lighting up the sky, while the tree is dim -- shining mostly by reflected light. The sprite was fleeting -- lasting only a small fraction of a second, while the tree is durable -- living now for many years. Both however, when captured together, appear oddly similar in this featured composite image captured early this month in France as a thunderstorm passed over mountains of the Atlantic Pyrenees.

On September 12, from a location just south of the Arctic Circle, stones of Iceland's modern Arctic Henge point skyward in this startling scene. Entertaining an intrepid group of aurora hunters during a geomagnetic storm, alluring northern lights dance across the darkened sky when a stunning fireball meteor explodes. Awestruck, the camera-equipped skygazers captured video and still images of the boreal bolide, at its peak about as bright as a full moon. Though quickly fading from view, the fireball left a lingering visible trail or persistent train. The wraith-like trail was seen for minutes wafting in the upper atmosphere at altitudes of 60 to 90 kilometers along with the auroral glow.

Venus has returned as a brilliant morning star. From a window seat on a flight to Mexico City, the bright celestial beacon was captured just before sunrise in this astronomical snapshot, taken on September 12. Venus, at the upper right, shared the early predawn skies with an old crescent Moon. Seen from this stratospheric perspective, both mountain peaks and clouds appear in silhouette along a glowing eastern horizon. The dramatic, long, low cloud bank was created by venting from planet Earth's active volcano Popocatépetl.

Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our own Milky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not included in Charles Messier's famous 18th century catalog. Since the galaxy's disk is inclined to our line-of-sight, long telescopic exposures often result in images that evokes a strong sense of depth. The effect is further enhanced in this sharp image by galaxies that lie beyond the gorgeous island universe. The most prominent background galaxies are about one tenth the apparent size of NGC 7331 and so lie roughly ten times farther away. Their close alignment on the sky with NGC 7331 occurs just by chance. Lingering above the plane of the Milky Way, this striking visual grouping of galaxies is known to some as the Deer Lick Group.
