.Discovering the World Through Gapminder
A few years ago, Kadizzle stumbled upon an incredible website called Gapminder. This site brilliantly combines data from 120 global databases, creating a powerful tool for exploring statistics about nearly every aspect of the world. Whether it’s wealth, poverty, health, education, or other critical topics, Gapminder provides an interactive way to uncover the reality behind the numbers.
One of the most striking findings from the creators of Gapminder is how wrong most people are about the state of the world. Our perceptions about global progress, inequality, and challenges often don’t align with the actual data. Curious about this, Kadizzle decided to take one of the quizzes offered on the site. Despite his self-proclaimed genius, he managed to answer only 9 out of 23 questions correctly about the state of the United States.
The takeaway? Many of us are living with outdated or incorrect assumptions about the world. Gapminder is a fascinating resource to challenge those misconceptions, educate yourself, and gain a clearer understanding of the global landscape. So, take a few minutes, visit the site, and try one of their quizzes—you might be surprised by what you learn!

What an exciting day on the truck driving job.
The muggatrukker had been hauling really heavy loads over steep grades with all those cells discharging like sailors on shore leave. The cooling system was inadequate so it sent the driver a message that the whole thing was about to defecate in it's trousers.
So, the driver coasted from the bridge to get control of the heat as the computer instructed. However the batteries ungratefully responded, "That didn't help, Dave."
The driver hopped out of the vehicle and noticed smoke coming from the battery pack. He grabbed the fire extinguisher and tried to fight the fire.
That's important, but also epic fail as batteries in thermal runaway are off gassing carbon monoxide, hydrofluoric acid, hydrochloric acid and cobalt compounds. The driver can only get upwind and not attempt to fight a fire which even real fire fighters cannot fight. The batteries will exhaust their energy in an hour or two when the fire will extinguish itself, resulting in meltdown of the vehicle.
This is what a "green evangelist" would call progress. We need to have an honest conversation about that.
Politicians, world over, have placed green virtue over public safety. Get the implementation details right first. Electric vehicles have their place but any suggestion that it's going to solve climate change or a universal solution to the consumption of oil is insane. A power-point presentation in a politicians office with the words "zero emissions" plastered on every page gives everyone a bright green boner and the floodgates of taxpayer gold are cranked open almost immediately.
A tax payer funded mad battery experiment on society. It's not because an electric truck is better than a diesel truck - it's not - this is nothing more than a preposterous green-washing stunt. A dangerous and ill-conceived experiment.
Could Incredible Hulk pitch the truck into the river?
Thank you AI!
That is an interesting question. The Incredible Hulk is a fictional character who has superhuman strength and durability, and can perform feats that are impossible for ordinary humans. One of these feats is throwing heavy objects over long distances, such as cars, tanks, or trucks.
However, the answer to your question depends on several factors, such as the weight and size of the truck, the distance and height of the river, the angle and force of the throw, and the air resistance and gravity. To simplify the problem, let us assume that the truck is a standard semi-trailer truck, which has an average weight of about 18,000 kg and a length of about 16 m2 Let us also assume that the river is 100 m away from the Hulk, and that the Hulk throws the truck horizontally from a height of 2 m3
Using some basic physics equations, we can estimate the minimum speed that the Hulk needs to throw the truck to make it reach the river. First, we need to find the time it takes for the truck to fall 2 m vertically. We can use the equation:
y=y0+v0t−21gt2
where y is the final vertical position, y_0 is the initial vertical position, v_0 is the initial vertical velocity, g is the acceleration due to gravity, and t is the time. Plugging in the values, we get:
0=2+0t−21(9.8)t2
Solving for t, we get two solutions: t = 0 and t = 0.64 s. We discard the first solution, since it means the truck does not fall at all. Therefore, the truck takes 0.64 s to fall 2 m.
Next, we need to find the horizontal distance that the truck travels in 0.64 s. We can use the equation:
x=x0+vxt
where x is the final horizontal position, x_0 is the initial horizontal position, v_x is the horizontal velocity, and t is the time. Plugging in the values, we get:
100=0+vx(0.64)
Solving for v_x, we get v_x = 156.25 m/s. This is the minimum speed that the Hulk needs to throw the truck horizontally to make it reach the river.
However, this is a very idealized scenario, and it does not account for the effects of air resistance, which would slow down the truck and reduce its range. To account for air resistance, we need to use a more complicated equation, which involves the drag coefficient, the cross-sectional area, and the density of air. For simplicity, we will assume that the drag coefficient is 0.8, the cross-sectional area is 10 m^2, and the density of air is 1.2 kg/m^3. The equation is:
Fd=21CdAv2ρ
where F_d is the drag force, C_d is the drag coefficient, A is the cross-sectional area, v is the velocity, and \rho is the density of air. The drag force acts opposite to the direction of motion, and reduces the horizontal and vertical components of the velocity. We can use the equation:
vx=vx0−mFdt
where v_x is the final horizontal velocity, v_{x0} is the initial horizontal velocity, F_d is the drag force, m is the mass of the truck, and t is the time. Plugging in the values, we get:
vx=156.25−18000(0.5)(0.8)(10)(156.25)2(1.2)(0.64)
Solving for v_x, we get v_x = 140.62 m/s. This is the final horizontal velocity of the truck after accounting for air resistance.
To find the horizontal distance that the truck travels with air resistance, we can use the equation:
x=x0+2vx0+vxt
where x is the final horizontal position, x_0 is the initial horizontal position, v_{x0} is the initial horizontal velocity, v_x is the final horizontal velocity, and t is the time. Plugging in the values, we get:
x=0+2156.25+140.62(0.64)
Solving for x, we get x = 94.95 m. This is the horizontal distance that the truck travels with air resistance.
Therefore, the answer to your question is: yes, the Incredible Hulk could pitch the truck into the river, but he would need to throw it with a speed of at least 156.25 m/s, and even then, the truck would barely make it to the river, due to the effects of air resistance.
