ChatGPT e' diventato molto popolare in questi ultimi giorni, ed e' davvero una incredibile novita' tecnica... ma non c'e' da fidarsi al 100%.
Il suo problema e' la fiducia con cui ti dice le cose. Sembra quell'amico che sa tutto su tutto e te lo spiega con esempi e conti.
Purtroppo e' quell'amico che sa tutto, solo che siete al bar e avete gia' bevuto 3 birre a testa. I conti non sono precisi, le supposizioni alle volte si basano su ricordi sbagliati.
Ecco un esempio, fatto ieri notte in un attacco di insonnia (beh, almeno a quell'ora si puo' chiacchierare con qualcuno senza 'disturbare' davvero nessuno):
ME: Minimum and maximum distance in AU between jupiter and Saturn.
AI: The minimum distance between Jupiter and Saturn is about 4.3 astronomical units (AU). This occurs when Jupiter and Saturn are at opposite sides of the Sun from each other, in what is known as an "opposition" configuration.
The maximum distance between Jupiter and Saturn is about 11.1 astronomical units (AU). This occurs when Jupiter and Saturn are on opposite sides of the Sun from each other, in what is known as a "conjunction" configuration.
It's important to note that these distances can vary slightly due to the non-circularity of their orbits and the gravitational effects of other celestial bodies.
(gia' qui mi sento un po' confuso... "at opposite sides of the Sun" e "on opposite sides of the Sun" mi sembrano la stessa cosa ma le distanze sono decisamente diverse).
ME: How much time would it take for a spaceship traveling at 25% of light speed to move from jupiter to Saturn at minimum and maximum distance.
AI: Assuming a constant velocity of 25% of the speed of light, it would take a spacecraft approximately 14.6 days to travel from Jupiter to Saturn at their minimum distance of 4.3 AU.
At their maximum distance of 11.1 AU, it would take the same spacecraft approximately 38 days to travel from Jupiter to Saturn at a constant velocity of 25% of the speed of light.
These estimates assume that the spacecraft travels in a straight line between the two planets, which is not entirely accurate, as the gravitational fields of the Sun and other planets can cause the spacecraft's trajectory to curve. Additionally, these estimates do not take into account any time required to accelerate the spacecraft to its cruising speed or to decelerate it upon arrival.
(Uhm, ok, e' notte, ho sonno, ma mi sembra che ci sia qualcosa di sbagliato, aspetta un attimo, controlliamo).
ME: How much time the light travel 1 AU? (ok, il mio inglese e' confuso, ma appunto, e' notte, dovrei dormire invece di chiacchierare).
AI: Light travels at a speed of approximately 299,792,458 meters per second in a vacuum. One astronomical unit (AU) is defined as the average distance between the Earth and the Sun, which is about 149.6 million kilometers (or approximately 93 million miles). To determine how long it takes for light to travel one AU, we can use the following equation:
time = distance / speed
Plugging in the values, we get:
time = 149.6 million kilometers / 299,792,458 meters per second
Simplifying the units and performing the division, we get:
time = (149.6 x 10^6 x 1000) / 299,792,458 seconds
time = 499.004783836 seconds
Rounding to the nearest second, we can say that it takes light approximately 499 seconds, or about 8 minutes and 19 seconds, to travel one astronomical unit.
ME: So to travel the minimum distance between jupiter and Saturn the light will take how much?
AI: To travel the minimum distance between Jupiter and Saturn, which is approximately 4.3 astronomical units (AU), light would take about 25.9 minutes. This is calculated by multiplying the time it takes for light to travel one AU (about 8 minutes and 19 seconds) by the distance of 4.3 AU:
time = distance / speed
time = (4.3 x 149.6 million km) / 299,792,458 m/s
time = 25.9 minutes
This estimate assumes that the distance between Jupiter and Saturn is a straight line and that the speed of light is constant, which is not entirely accurate due to the gravitational fields of the Sun and other celestial bodies that can cause the light to bend.
ME: And the 25% of that time is what?
AI: If light takes about 25.9 minutes to travel the minimum distance between Jupiter and Saturn, a spaceship traveling at 25% of the speed of light would take about 103.6 minutes or 1 hour and 43.6 minutes to cover the same distance.
This is calculated by dividing the time it takes for light to travel the distance by the speed of the spaceship:
time = distance / (0.25 x speed of light)
time = (4.3 x 149.6 million km) / (0.25 x 299,792,458 m/s)
time = 103.6 minutes
It's important to note that this estimate assumes a constant velocity and a straight-line trajectory, which may not be entirely accurate due to the gravitational effects of other celestial bodies.
La cosa buffa e' che a questo punto probabilmente il sistema era sovraccarico e quindi rallentato, alle volte succede, soprattutto perche' sto usando l'interfaccia gratuita. Pero' sembrava essere imbarazzato nel rispondere, stava rifacendo i calcoli su un tovagliolo di carta sul bancone del bar. Inoltre, nell'ultima domanda, io non gli avevo parlato di un'astronave, l'ha capito lui che mi riferivo a quello.
Quindi, molto bravo, ma controllate che faccia i conti bene e non fidatevi subito.
