In electrodynamic suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields.  In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system.  The magnetic field is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable – changes in distance between the track and the magnets creates strong forces to return the system to its original position.  In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed.
I have been om t bol for 7 days 20-30 mg taken pils every 24 hour , i decided to drop cycle and continue naturally Because i got depressed just by an idea that im doing steroids and they can permanently destroy my natural t , i have been of for over 30 hours . I experienced tiredness and little lower libido but can still Get erection If i watch porn s little harder though since im thinkin all day long that i have fucked up my natural t , i have nolvadex and blackstone labs pct which has tribulus SAW palmetto n acetyl cystene , androst 3,5 -dien-7, 17 dione and alpha hydroxy laxigene and i have A test booster with daa. I done 7-8 months ago t bol cycle of 5 weeks same tabs underground from exactly same package im unsure If caps really contain 20 mg but i dont think is d bol because i didnt gain mu h weight on cycle 7-8 months ago . Im getting some clomid In 5-6 days then ill add. Clomid 25 mg and lower nolva to 10 mgs and run the pct for 3 weeks . Remember i have been on tbol only for A week first three days 20 mg 4th day 30 5th day 20 , 6th day 20 , 7th day 30 and 8th day only 10 , 30+ hours ago . I have been on cut but now im quitting earliwr because im scared that i supressed my hpta during 1 week on t bol , balls seem fine but im not getting morning woods i usually dont Often Get them but i have had some before this cycle . I have been depressed this week and the only one thing im thinking off is that i destroyed my natural t , maybe all this is psychological but i wont really Do any cycle ever again and want to stay natty , what should i Do run nolva first week 20 mg then lower IT to 10 and add clomid together with blacstone pct for 3 weeks , i am really unsure on PCt is IT better to run IT or not since i have been on for such A short time and should i drop cutting or should i continue , please answer me i will appreciate any kind of help i have such anxiety about that i have messed myself up
This is an investigation of whether the real world behaves as predicted by the hypothesis. Scientists (and other people) test hypotheses by conducting experiments . The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases. Agreement does not assure that the hypothesis is true; future experiments may reveal problems. Karl Popper advised scientists to try to falsify hypotheses, ., to search for and test those experiments that seem most doubtful. Large numbers of successful confirmations are not convincing if they arise from experiments that avoid risk.  Experiments should be designed to minimize possible errors, especially through the use of appropriate scientific controls . For example, tests of medical treatments are commonly run as double-blind tests . Test personnel, who might unwittingly reveal to test subjects which samples are the desired test drugs and which are placebos , are kept ignorant of which are which. Such hints can bias the responses of the test subjects. Furthermore, failure of an experiment does not necessarily mean the hypothesis is false. Experiments always depend on several hypotheses, ., that the test equipment is working properly, and a failure may be a failure of one of the auxiliary hypotheses. (See the Duhem–Quine thesis .) Experiments can be conducted in a college lab, on a kitchen table, at CERN's Large Hadron Collider , at the bottom of an ocean, on Mars (using one of the working rovers ), and so on. Astronomers do experiments, searching for planets around distant stars. Finally, most individual experiments address highly specific topics for reasons of practicality. As a result, evidence about broader topics is usually accumulated gradually.
